green coke

Green coke raw 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, 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.

Note:

Raw coke is an equivalent term to green coke although it is now less frequently used. The so-called volatile matter of green coke depends on temperature and time of coking, but also on the method for its determination.
