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 forms: graphite and diamond. Each has its own distinct crystal structure and properties. Carbon black consists of planes of carbon atoms fused together randomly to form ...

From a physical standpoint, it has hardness from 30 to 100 HGI, shot content from 0% to and comes in various granule sizes of between 0 mm and 50 mm. Fluid coking, to obtain fluid petcoke is a continuous process of pulverization at high temperatures on a fluid surface in which the coke particles are maintained at a pressure of between 20 ...
The size of the chemical coke charged into electric reduction furnaces must be smal- ler than that of blast furnace coke. To obtain this small size the larger coke from coke ovens must be crushed, usually to a top size of about 314-inch. Very small sizes must be screened from the crushed coke, leaving an acceptable size of about 3/4" ~1/8".

resistance of the setup was measured by running a test without a sample in the setup. Using the standard-like two-probe method, a resistivity of 478.3 lX m was obtained for coke A, while it was 483.7 lX m for coke B. For the same materials, the four-probe method gave 386.2 and 418.5 lX m for cokes A and B, respectively.
