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.
