Green Coke
Green coke, also known as raw coke, is the primary solid carbonization product from high-boiling hydrocarbon fractions obtained at temperatures below 900K. It contains a fraction of matter that can be released as volatiles during subsequent heat treatment at temperatures up to approximately 1600 K. This mass fraction, the so-called volatile matter, is in the case of green coke between 4 and 15 wt%, but it depends also on the heating rate.
