green coke
Green @C01142@ (@R05158@) is the primary solid @C00840@ product from high boiling hydrocarbon fractions obtained at temperatures below \(900\ \text{K}\). It contains a fraction of matter that can be released as volatiles during subsequent heat treatment at temperatures up to approximately \(1600\ \text{K}\). This @M03722@, the so-called volatile matter, is in the case of green @C01142@ between 4 and 15 wt.%, but it depends also on the heating rate.
@R05158-1@ is an equivalent term to green @C01142@ although it is now less frequently used. The so-called volatile matter of green @C01142@ depends on temperature and time of @C01144@, but also on the method for its determination.
