green coke

(or raw coke)

1. This 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%, but it depends also on the heating rate. (IUPAC 1995).

2. Usually refers to calcineable coke, i.e., potential anode quality coke that still contains moisture and volatile material, i.e., before calcining.
