Green coke

Carbonization product

Green coke is the primary solid carbonization product from high boiling hydrocarbon fractions obtained at temperatures below 900 K. 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, called volatile matter, is in the case of green coke between 4 and 15 wt.%, but it depends also on the heating rate.
