Petcoke

Petroleum Coke is a solid, carbon-rich material, derived from crude oil refining. More specifically, coke is a bottom of the barrel by-product, result of the end of the cracking process. It is a grayish-black solid, that is usually distinct in two varieties: fluid coke, and flexicoking coke (although other classifications are used, such as needle, honeycomb, sponge, shot and others). Fluid coke, or green coke, is obtained from delayed cooking processes and the flexicoking are fine grained, with a great level of isotropy. There is also calcinated coke, which is a product of green coke, after above 1300°C heating.
