Calcined petroleum coke  is the product from calcining petroleum coke. This coke is the product of the coker unit in a crude oil refinery. used to make anodes for thealuminium, steel and titanium smelting industry.

 

The green coke must have sufficiently low metals content in order to be used as anode material. Green coke with this low metals content is referred to as anode grade coke. The green coke with too high metals content will not be calcined and is used for burning. This green coke is called fuel grade coke.
