Petroleum Coke CAD Revised 8-22-2008 Consortium Registration #1100997 i PETROLEUM COKE CATEGORY ANALYSIS AND HAZARD CHARACTERIZATION Submitted to the US EPA by The American Petroleum Institute Petroleum HPV Testing Group Consortium Registration # 1100997 Revised August 22, 2008 .
Petroleum coke, abbreviated coke or petcoke, is a byproduct of the oil refining process. As global refineries seek to operate more efficiently and extract more gasoline and other high value fuels from barrels of crude oil, a solid carbon material known as petcoke is produced. Petcoke is the coke that particularly derives from a final cracking ...
Petroleum coke is a hard solid petroleum product in black or dark gray, and is characterized by metallic luster and porosity. It is carbon-shaped stuff composed of tiny graphite crystals formed into granules, columns or needles. The composition of petroleum coke is hydrocarbons, containing 90-97% carbon, 1.5-8% hydrogen, and elements such …
Hebei Fangke New Material Technology Co., Ltd located in Handan City, Hebei Province, is a new energy enterprise integrating the production and sales of CPC. The factory was established in 2012 and covers an area of 40 hectares. It has more than 350 employees and its main products are prebaked anode raw materials used in the aluminum industry, …
Hardness: There are two distinct varieties of petcoke: calcined and uncalcined. Calcined petcoke is more complex and denser than regular petcoke due to …
Sponge Petroleum Coke Quality. Sponge petcoke produced from low grade crude oil contains higher levels of sulphur and heavy metals and is mainly used a solid fuel for power generation, cement kilns and other industrial applications. Fluid petcoke due to its high sulfur content and hardness is almost exclusively used as fuel.
Petroleum coke (petcoke) is the gray-to-black solid carbonaceous residue left by the destructive distillation of petroleum residua. Carbon has two natural crystalline allotropic …

Differences in fines fraction and hardness of cokes from rotary kilns and shaft calciners can also drive additional ... petroleum coke (CPC) from different green petroleum coke sources (GPC). Based on sulfur content, these cokes being blended to achieve *2.5% Sulphur in CPC. Blending
petroleum coke does not meet the screening criteria for bioaccumulat ion. No chronic aquatic toxicity studies are available for calcined petroleum c oke. However, acute toxicity studies on green petroleum coke showed EC50 values of >1,000 mg/L the nominal WAF loading rate. Thus calcined petroleum coke does not meet the screening criteria for ...
(2) During the steelmaking process: calcined petroleum coke and graphitized petroleum coke are added to the molten steel as carburizing agents to increase the carbon content and hardness of the ...
It is produced by combining silica (silicon dioxide) and petroleum coke at high temperatures in electric resistance furnaces. Carborundite is primarily used as an abrasive material for grinding, cutting, polishing, and sanding. Its exceptional hardness, with a Mohs hardness rating of 9-9.5, makes it suitable for wear-resistant applications.
At the surface, the amount of OFPW is separated from crude oil, but small suspended oil particles, Oil and Grease (O&G), dissolved organic and inorganic compounds mainly Chloride ion (Cl −), Bicarbonate ion (HCO 3 −), Carbonate ion (CO 3 2−) and Sulphate ion (SO 4 2−) still remain, making the discharge of OFPW an …
The bending strength and hardness of the phenolic resin-based friction composites (CPC-1A, CPC-0.75A, CPC-0.5A, CPC-0.25A, and CPC-0A) are shown in Table 1. It is seen that the incorporation of calcined petroleum coke (CPC) led to a gradual increase in the hardness and in the bending strength of the phenolic resin-based friction …
