This week, the mainstream price of the cathode carbon block market was stable, and the overall trading volume was relatively stable. The price of raw calcined anthracite and low sulfur calcind pet coke was stable, but the price of coal tar pitch rebounded and supported, supporting the price of cathode carbon block, but the overall support was limited.
Production: The overall market start-up was stable compared with last week, but due to strict environmental protection inspection, the construction of Shanxi in the main producing area was slightly lower than before. The cathode production in the southwestern region was completely stopped. The enterprises in Central China and Northwest China started normally, but the start-up of individual enterprises was started. Low, mainly produces other products.
In terms of market trading: The market currently implements more fixed orders. In the first half of 19 years, most of the orders have been signed, including domestic sales and exports.
1. Shanxi Province issued the “Action Plan for Air Pollution Prevention and Control in Shanxi Province in 2018”. The plan points out that the most stringent system and the most powerful measures are taken to ensure air quality.
2, Shanxi Jinzhong issued the "Jinzhong City Air Pollution Prevention and Control 2018 Action Plan." Implement environmental protection upgrading projects for industrial enterprises. Since August 20th, the environmental inspection team has been inspected and continued until November, when the problem enterprises are rectified. Deep treatment is expected to be completed in mid-December.
Production: The environmental protection situation in the main producing area of Shanxi Province entering the heating season is severe, and with heavy pollution, individual companies are being looked back to see the production reduction.
Production in the heating season in Henan is not affected by environmental protection; in the southwest region, Sichuan enterprises suspend production, main processing, etc.; Northwest enterprises produce normal; most enterprises have signed orders until June 2019, the national cathode carbon block cathode carbon block total national The production capacity is more than 600,000 tons, of which about 70% of the production capacity is concentrated in Jinzhong City, Shanxi.
Shanxi Province has a production capacity of 460,000 tons and a production of 19,800 tons in November. 2. The production capacity of Hebei Province is 25,000 tons, and the output in November is 500 tons. 3. 50,000 tons in Henan Province and 500 tons in November. 5. The Ningxia Autonomous Region has a production capacity of 4 tons and a production capacity of 1,500 tons. 6. Yunguichuan's production capacity is 49,000 tons, all of which are in production.
Cathode carbon block capacity utilization rate is low, and graphitized enterprises have many external processing graphite electrodes, which is also the main factor for the reduction of cathode carbon block production.
Low-sulfur calcined petroleum coke: This week, the low-sulfur calcination coke market is not well-sold, the downstream enterprises have reduced the procurement of raw materials, and there is a phenomenon of price reduction. Most of the low-sulfur calcination coke production enterprises have inventory in this week, and the transaction price has dropped significantly. According to the understanding, there is no significant change in the trading of low-sulfur Fushun calcined coke this week, and the price remains stable.
Downstream: Baichuan Information Statistics: As of December 20, 2018, China's electrolytic aluminum production capacity was 46.956 million tons, starting at 35.758 million tons, and the operating rate was 76.15%.

Market outlook: The downstream electrolytic aluminum market is operated at a low level by aluminum prices, and the market's production reduction has increased. The company has stopped production and repairs, which is good for cathode consumption and increases corporate orders.
2018.11.25 This week, the overall mainstream price of China's carbon refining agent market remained stable, and market trading was relatively stable. Among them, the low-quality general-purpose calcination and refining agent market is generally traded, and individual enterprises are out of stock, and the company is close to the annual customs. Ningxia, the main producing area, is affected by environmental protection, and the cost of enterprises has increased. However, the company has experienced the construction of closed raw material warehouses and the renovation of environmental protection equipment. At present, it can be produced normally; the medium and high grade recarburizer market is generally good, but there are still some The sound of goods blocked is mainly due to the general operation of the downstream market, and the demand is limited. At the same time, the graphitization of the negative electrode enterprises in Inner Mongolia has increased, which has a greater impact on the market.
General calcined coal recarburizer:
2018.11.25 This week, the mainstream price of China's general calcined recarburizer market was stable, and the overall market trading was relatively stable. The market reaction was still a little difficult. Production: As the main production area, the current production of Ningxia enterprises is relatively normal, and the inventory of individual enterprises is relatively high, mainly based on stocks. Due to the limited demand in the downstream market, enterprises mainly rely on maintaining fixed customers, and entering the heating season. Environmental protection is more stringent. Enterprises in Inner Mongolia are producing normally and are generally shipped. The prices of raw materials are stable, and the pressure on production costs of enterprises is limited. However, in view of environmental management and control, the management of enterprise yards and environmental protection equipment, the pressure is still high and the operating costs are high. As the heating season continues to deepen, the supervision will continue to escalate and the market will start to be limited.
Downstream: Domestic steel prices have fallen sharply this week. The demand side gradually shrank, the period snail fell sharply, the market bearish sentiment was heavier, and they all dropped their prices. Leading steel mills are weak, and prices have fallen sharply. Although social stocks continued to decline, the decline gradually narrowed. In the second half of the cycle, the market stopped falling and rebounded, and the market mentality gradually stabilized. It is expected that short-term domestic steel prices may be consolidating and running. It is expected that short-term domestic steel prices may be consolidating and running, or there may be a slight oversold rebound.
Calcined petroleum coke recarburizer:
2018.11.25 This week, the mainstream price of China's calcined coke recarburizer market remained stable, and the overall market trading volume was relatively stable. Production: At present, local environmental protection policies have been introduced one after another. The distribution of carbon refining enterprises is relatively wide, especially in Shandong, Tianjin and Liaoning. The environmental protection pressure is relatively high. At present, enterprises mostly reflect normal production, but with the continuous deepening of the heating season. Increased heavy pollution weather may limit production. In the short term, prices are mainly stable.
Raw materials: medium and high sulfur calcined coke: 2018.11.25 This week, the market for high-sulfur calcined coke was poorly shipped, and the overall market turnover was sluggish. The mainstream transaction price continued to fall by RMB 50/ton from last week. On the supply side, this week, the carbon companies in Nangongyi and Fuyang districts have been shut down for production. Currently, two calcined coke enterprises in the district are about to stop production. Most of the production enterprises in Shandong, Hebei, Jiangsu and other places performed normally. In addition, in view of the recent sluggish market conditions, some production companies have begun to reduce production; in terms of demand, the demand for medium-high sulfur calcined coke has remained stable this week, and the export market remains unsupported.
Graphitized petroleum coke recarburizer:
2018.11.25 This week, the market price of China's graphitized petroleum coke recarburizer was stable. The raw material petroleum coke price is weak and stable, and the support for graphitized recarburizer is limited. Production: In the Henan and Xinjiang regions, the production of enterprises in Henan and Xinjiang was suspended due to environmental protection, and the operating rate declined. The enterprises in Jiangsu, Tianjin and Inner Mongolia started to work stably. In addition, the graphitization enterprises of anode materials in the Inner Mongolia market started to work, and the release of graphitized production increased. Demand: At present, most of the enterprises are mainly to maintain fixed customers. With the production of negative electrode factories in Inner Mongolia, the enterprises have higher filling materials and are filled with the market consumption of recarburizers. The market is under pressure. Inner Mongolia Xingfeng New Energy Technology Co., Ltd. will start production in 300,000 tons per year. The production capacity will lead the refining agent market. Enterprises in Jiangsu Province have normal production, good shipments and smooth exports.
Forecast: Raw material prices are weak, which is unfavorable to the price of recarburizers; at present, most of them are based on maintaining fixed orders, and the overall performance is relatively mild and general, and individual enterprises are in stock. With the increasing environmental protection and the deepening of the heating season, the production side of the company may be limited. Therefore, the short-term low-grade recarburizer will be stable, and the price of medium- and high-grade recarburizers will be weak. It is expected to be reduced by 200 yuan/ton.
20181012 This week, the mainstream price of China's carbon-reducing agent market was stable, the market for low-grade recarburizers was generally trading, the inventory of enterprises was high, and the market for medium and high recarburizers was better. The heating season is just around the corner, the downstream steel mill's production restriction policy is clear, the company's operating rate is low, and the receiving sentiment is relatively dull. The market price of the refining agent is generally stable, and the possibility of deposit and landing is high. The prices of raw materials in the medium and high grade recarburizer market were generally raised after the holiday, and the cost pressure of production enterprises increased. However, given the limited acceptance capacity of the downstream market, the company's quotation has not been raised.
General calcined coal recarburizer:
This week, the mainstream price of China's general calcined carbonizer market remained stable, and the overall market shipments were generally due to the general consumption of downstream steel mills, and the demand was relatively light. Most of the manufacturers of ordinary calcined carbon refining agents are electric calcined anthracite enterprises, which are self-produced and screened. The environmental protection facilities of local enterprises in the main producing area in Ningxia will be inspected in succession in October, or the market will be affected later. The production of enterprises in North China is normal, but the reaction starts low, the market is generally trading, and the enterprises have inventory.
Downstream: China's construction steel prices have risen slightly this week. From a fundamental point of view, although the inventory has increased this week, compared with the same period of last year, the inventory level is still low, so the balance of supply and demand has not been broken, the steel market is still supported. With the arrival of "Silver Ten", after the high expectations in September fell, the market did not dare to have much expectations for October, and the confidence was obviously insufficient. However, the construction period that fell for various reasons in the early stage should have a wave of work, the relative demand. There will be some release. If there is support in the policy, "Silver Ten" can still look forward to it. Considering comprehensively, it is expected that the short-term building materials market will still rise slightly, with a range of 50 yuan/ton.
Calcined petroleum coke recarburizer:
This week, the mainstream price of China's calcined coke market was stable, and raw material prices rose slightly. However, in view of the environmental impact of downstream enterprises, the low starting price, the demand for carbon-reducing agents is relatively stable, the market is generally trading, the late heating season comes, and the price of calcined coke Or it will fluctuate due to limited production, affecting the shipment of recarburizers, or will benefit other quality recarburizers. This week, the medium-high sulfur calcined coke market was trading well, and the monthly order prices of individual companies increased slightly. Up to now, the production profit of most calcined coke enterprises is still acceptable, which is significantly improved compared with the previous three quarters, and the production enthusiasm has improved. The operating rate of calcined coke enterprises in Shandong and Jiangsu increased this week; the Henan and Hebei regions started to work stably.
Graphitized petroleum coke recarburizer:
This week, the market price of China's graphitized petroleum coke recarburizer was stable. The price of raw materials, petroleum coke, rose after the holiday, and the overall price was generally raised. The pressure on the production cost of recarburizer increased. Among them, the production of individual enterprises in Henan and Xinjiang was suspended due to environmental protection, and the operating rate fell. In addition, the graphitization enterprises of anode materials in the market will start construction in the second half of the year, and the output will be released. Graphitization and recarburizers are highly concentrated in Inner Mongolia. Enterprises in Jiangsu Province have normal production, good shipments and smooth exports.
Market outlook: The market for general calcination and recarburization is currently trading, and the inventory of enterprises is higher, but the price of raw materials for electric calcined coal may be low due to limited production, stimulating the price of recarburizer; among them, calcined coke and graphitized recarburizer Price companies are driven by cost, pressure is increasing, and prices are pushing up.
For casting, cast iron, cast steel, and castings all have a requirement for carbon. Then, as the name suggests, the carbonizer is used to increase the carbon content in the molten iron. For example, in the smelting, the common charge is pig iron, scrap steel, and recycled material. The carbon content of pig iron is high, but the purchase price is higher than that of scrap steel. Therefore, increasing the amount of scrap steel, reducing the amount of pig iron, and adding carbonizer can play a role in reducing the cost of castings. If you want to use high-quality recarburizer, then non-graphite recarburizer is the only one, because the graphitization of the recarburizer, the carbon element arrangement has changed, the carbonization effect is better!

Calcined coke, is obtained by calcining raw petroleum coke at a high temperature of 1300 ° C. After calcination, the petroleum coke has higher carbon content and less impurities, and is usually used as a recarburizer.
Low-sulfur calcination coke: The market price of low-sulfur calcined coke price is relatively stable this week. The performance of low-sulfur calcination coke is general. Some enterprises have obvious inventory. The market price of downstream graphite electrode has risen slightly this week, but the raw materials of enterprises are still pressed. Need to purchase, and the operating rate is limited due to environmental impact. Among them, Fushun and Daqing are still poor in calcined coke, raw materials continue to increase, and raw materials prices are insured at this month, and downstream purchases are mostly on demand. The willingness to sell goods, while the production companies continue to cut prices and promote the willingness to clear the library again. Low-sulfur calcination coke recarburizer market coking is slowing down this week. On the one hand, the downstream purchasing enthusiasm has declined after the price rise. On the other hand, this week, the Liaohe Petroleum Exploration Bureau Co., Ltd. Petrochemical Branch has started a rotary kiln this week. The market share has shifted.
Medium and high sulfur calcined coke: This week, the domestic medium and high sulfur calcined coke market was stable, and the coke price was unchanged from last week. Due to the recent decline in the price of raw petroleum coke, the profits of calcined enterprises have increased significantly, some enterprises have increased production load, the market supply has increased, and the market for medium and high sulfur calcined petroleum coke is no longer in short supply. This week, environmental protection has not affected the production of calcined enterprises in various regions. The calcined coke in Henan has resumed normal production. At present, the daily output is about 100 tons, and the production of raw goods is calcined. The carbon company in Shandong is ignited this week, and the plant is finally prebaked. It is expected that the calcined coke will be put into the market in the early stage. It is understood that at present, most of the calcined coke production enterprises are mainly engaged in the implementation of pre-contracts. For the time being, most of them have no inventory pressure. Recently, the downstream part of the contract has begun to reduce prices, and the late coke price still has downside risks.
Market outlook: low-sulfur common quality calcined coke market is expected to continue to move smoothly before the holiday, in which the price of low-sulfur high-quality calcined coke will continue to fall next week; most companies in the medium-high sulfur calcined coke market are full of orders this month. Therefore, the transaction price is expected to remain stable next week, but due to the current downward adjustment of raw material prices, it is expected that the post-holiday price will be lowered.

The three major groups of petroleum coke market:
In terms of Sinopec, most of the refinery's petroleum cokes are stable today, and only a few refineries have lowered their prices by 40 yuan/ton. Recently affected by typhoon mangosteen, last week, Guangzhou, Maoming Petrochemical and other refinery oil coke shipments were suspended for one day, and today returned to normal, Guangzhou Beihai refinery petroleum coke shipped normally. Jinshan Petrochemical Petroleum Coke in East China began exporting petroleum coke on September 14th, with a daily output of about 1,000 tons. The Jingmen petrochemical coking unit along the Yangtze River is expected to start on September 9. The Shengli petrochemical coking unit in Shandong has been shut down for maintenance on the 9th day and is scheduled to be shut down for 55 days.
In the case of PetroChina and CNOOC, the price of the petroleum coke market in the Northeast region was generally stable, and most of the refinery oil coke trading performed well. There is no price fluctuation in the petroleum coke in the northwest. CNOOC Zhoushan Petrochemical today's heavy rain, equipment maintenance time is expected to be postponed, and Huizhou Petrochemical due to the impact of typhoon, today's petroleum coke suspended delivery.
Refining petroleum coke: Today's refining petroleum coke market is not well shipped, and the market trading atmosphere is generally weak. The low-end price of the market is stable, and the high-end price is rationally reduced. The concentration is 20-50 yuan/ton. In terms of refinery dynamics, Yanqiao Petrochemical Coking has not yet started, and it is expected to start construction in the next 2-3 days; Jincheng Petrochemical Petroleum Coke will measure 1.2-1.7% of sulfur.
Calcined petroleum coke market: Today, the market for calcined coke is stable, the market price has not been adjusted, and the overall market is well shipped. The low-sulphur calcined coke screening continued to perform well in recent shipments, especially the shipment of calcined coke between 0.6-1.5% of sulfur continued to perform well, due to the small market resources and the price continued to be firm. The trading of medium and high sulfur calcined coke market tends to be stable. On the one hand, the price of raw petroleum coke is falling steadily. On the one hand, the domestic calcined coke enterprises are stable, and the price of coke is still rising.
180912 petroleum coke and related calcined coke recarburizer market analysis, calcined coke, that is, the product of calcined petroleum coke, also called calcined coke, calcined petroleum coke is mainly used for prebaked anode used in electrolytic aluminum, metallurgical steel industry production Reinforcing agent, graphite electrode, industrial silicon, etc. Therefore, the supply of petroleum coke as a raw material for calcined coke recarburizer is closely related!
The three major groups of petroleum coke market:
In terms of Sinopec, the price of petroleum coke in its refinery is stable throughout the day. The refineries in Yanjiang and parts of East China continue to ship well. The oil coke in North China is relatively stable. The high-sulfur coke in South China has been trading in general. Some refineries Stock appears. The price of Tahe and Yangzi Petrochemical is increased by RMB 20/ton. In terms of refinery installations, the Jingmen Petrochemical coking unit in the Yanjiang area continued to be shut down for maintenance this week. Therefore, the petroleum cokes of Wuhan Petrochemical, Jiujiang Petrochemical, Changling Petrochemical and Jinao Petrochemical were still well shipped.
The commencement of the 2# coking unit of Jinshan Petrochemical in East China is expected to be postponed until the beginning of October, but the plant is expected to have an export plan in late September. The price of Yangzi Petrochemical's iron transportation was pushed up today, which was in line with the price of steam transportation, and the advantage of railway transportation was weakened. The Yanshan petrochemical coking unit in North China began to defocus normally on Friday. The recent petroleum coke of Yanzhou Petrochemical is still mainly based on 3#B shipment. It is expected to start production of 4#A indicator around 9.15.
In the case of PetroChina and CNOOC, Binzhou Zhonghai Asphalt was shut down for maintenance this week, which is good for Tianjin Dagang Petrochemical's low-sulfur coke market. However, the market price of low-sulfur petroleum coke was stable this week. Due to the continuous downward trend of coking prices, the price of Jilin and Liaoyang Petrochemical will also be stable this week. In the northwest region, Yumen, Lanzhou Petrochemical and other medium-sulphur cokes were well-sold, and the prices of petroleum cokes in various refineries in Xinjiang were stable. This week, Taizhou Petrochemical and Huizhou Petrochemical's coke prices were temporarily stable.
Refining petroleum coke:
Today, the price of refining petroleum coke is still the following behavior, the mainstream range is 30-50 yuan / ton. It is understood that the refinery's petroleum coke shipments, which have been lowered in focus, have changed. Most refineries are over-priced in the early period.
Calcined coke market:
The mainstream price of calcined coke recarburizer was stable and the market was stable. In the northeast and north China, the production of enterprises is stable, the price of calcined coke is rising, and the cost pressure of enterprises is increasing. However, in view of the high price in the downstream market, the price intention is weak, the production enterprises are still shipping, and the mainstream prices of the market have not yet fully fluctuated. Medium and high sulfur calcined coke: The price of domestic medium and high sulfur calcined coke continued to rise this week. The mainstream range was 50-100 yuan/ton, and the overall market turnover improved.
Foshan Yoshida Casting Materials Co., Ltd. has long-term supply of various particle size indicators of recarburizers, calcined coke recarburizers and graphitized recarburizers. There are various indicators, and the particle size can be selected according to customer needs.
The calcined coke recarburizer is obtained by calcining petroleum coke, also called calcined coke, calcined petroleum coke. The main component is carbon. Its role is to increase carbon as its name suggests. However, the quality of different recarburizers is not the same. The higher the carbon content, the lower the basic impurities (basic impurities refer to ash, volatiles, moisture, etc.). Another one is the sulfur and nitrogen content in the composition. The role of sulfur is basically clear. The inclusion of a certain amount of sulfur in the cast iron can better improve the physical properties of the casting. In recent years, the nitrogen content has also been extensively studied. The nitrogen content is too high, nitrogen holes are generated, the nitrogen content is too low, the hardness of the castings is not high, and the ferrite is much.
The role of the calcined coke recarburizer is for casting cast iron and cast steel. Castings have a requirement for carbon, so the recarburizer is used to increase the carbon content of the molten iron. The common charge in smelting is pig iron, scrap steel, and recycled material. The carbon content of pig iron is high, but the purchase price is higher than that of scrap steel. Therefore, increasing the amount of scrap steel, adding high-quality recarburizer, reducing the amount of pig iron added, saving production costs and meeting the production needs. The recarburizer is slightly different for each batch. You have to be a specific percentage, which is not realistic. Other ingredients are ash, moisture, sulfur, phosphorus and the like.
Graphite recarburizer has high degree of graphitization, low sulfur, low nitrogen, less harmful impurities, very fast dissolution, no absorption, no residue, no floating, no residue, less added; low sulfur and low nitrogen, very graphitized High, very suitable for all (or most) use of shavings, cold-filled materials, briquettes, wire, particle steel as raw materials, smelting vermicular cast iron, ductile iron, gray cast iron. We will provide targeted recarburizers according to the characteristics of different customers' process castings, and it is not expensive to ensure that the products are easy to use!
Scope of application: It is used for carbonization of cast iron and cast iron in various electric furnaces. It is especially suitable for the ball mill cast iron industry with strict requirements on product quality and strict sulfur control. Compared with other types of recarburizers, it has an absolute price advantage. The intermediate frequency furnace of half a ton to 12 tons, the furnace temperature is controlled at about 1500 degrees. The absorption rate can reach up to 93%.
1. The most important component of the calcined coke recarburizer is carbon. Its role is to increase carbon as its name suggests. However, the quality of different recarburizers is not the same. The higher the carbon content, the lower the basic impurities (basic impurities refer to ash, volatiles, moisture, etc.). Another one is the sulfur and nitrogen content in the composition. The role of sulfur is basically clear. The inclusion of a certain amount of sulfur in the cast iron can better improve the physical properties of the casting. In recent years, the nitrogen content has also been extensively studied. The nitrogen content is too high, nitrogen holes are generated, the nitrogen content is too low, the hardness of the castings is not high, and the ferrite is much.
2. The role of the post-calcined coke recarburizer is for casting cast iron and cast steel. Castings have a requirement for carbon, so the recarburizer is used to increase the carbon content of the molten iron. The common charge in smelting is pig iron, scrap steel, and recycled material. The carbon content of pig iron is high, but the purchase price is higher than that of scrap steel. Therefore, increasing the amount of scrap steel, adding high-quality recarburizer, reducing the amount of pig iron added, saving production costs and meeting the production needs. The recarburizer is slightly different for each batch. You have to be a specific percentage, which is not realistic. Other ingredients include ash, moisture, sulfur, phosphorus and the like. High-quality recarburizers generally refer to graphitized recarburizers. Under high temperature conditions, the arrangement of carbon atoms is in the microscopic form of graphite, so it is called graphitization. Graphitization can reduce the content of impurities in the recarburizer, increase the carbon content of the recarburizer, and lower the sulfur content, so the price is relatively high.
3. Conventional particle size of calcined coke recarburizer: small particle size: 0-1mm, 0.5-2mm, 0-2mm, etc.; medium grain size: 1-3mm, 0-3mm, 0-5mm, 1-5mm, 3-5mm , 3-8mm, etc.; Large particle size: 8-30mm, etc., but the actual use requirements also have various particle sizes, and the screening plant can screen out various particle sizes.
4. The particle size of the recarburizing agent is too thin to be easily burned. When it is too thick, it floats on the surface of the molten steel and is not easily absorbed by the molten steel. The particle size of the induction furnace is 0.5-6mm, wherein the steel and other ferrous metals have a particle size of 1-8mm, the high carbon steel requires low nitrogen, the particle size is 1-5mm, etc., and the specific needs of the workpiece are smelted according to the specific furnace type. The specific details and selection of the types and the like.
The general requirements for carbon refining agents for steelmaking or cast iron are:
1. The fixed carbon should be high, the content of ash, volatile matter and sulfur, phosphorus, nitrogen and other impurities should be low, and should be dry, clean and moderate in particle size.
2. Its fixed carbon ≥ 98%, volatile matter ≤ 1.0%, S ≤ 1%, moisture ≤ 0.5%.
The calcined coke recarburizer produced by Foshan Yoshida Foundry Materials Co., Ltd. can meet this requirement and has the characteristics of low melting point and high absorption rate. The calcined coke recarburizer has no effect on the chemical composition of steel, total inclusions, crystallinity, grain structure and mechanical properties, and the quality pass rate of steel is 100%.
Calcined petroleum coke is a high purity carbon material produced by heating green petroleum coke to drive off moisture, volatile matter, and impurities and to increase its electrical conductivity, which is used to improve the carbon content in steel-making and ductile iron foundry. It is widely used to produce graphite electrode, graphite blocks, brakes pads and other carbon products. it can also be used as carbon additive in some steel and aluminum plants, another, it is used in refractory, insulation, filler,etc. We can supply different grades of Calcined Petroleum coke.
The main application of Calcined Petroleum coke is in the production of anodes for the Aluminum Smelting process. 70 - 80% of CPC is for the Aluminum Industry. The reason for use in the Aluminum Industry is for conductivity.
Another used for Calcined Petroleum coke is TiO2 production which accounts for about 15% of the Calcined Petroleum coke consumption. The reason for use in TiO2 is for its oxidizing effect.
