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.
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 cooking, but also on the method for its determination.
Famous quotes containing the words green and/or coke:
“And nothing I cared, at my sky blue trades, that time allows
In all his tuneful turning so few and such morning songs
Before the children green and golden
Follow him out of grace.”
—Dylan Thomas (1914–1953)
“One of the oddest episodes I remember was an occasion in which [Clarence] Thomas was drinking a Coke in his office, he got up from the table, at which we were working, went over to his desk to get the Coke, looked at the can and asked, “Who has put pubic hair on my coke?””
—Anita Hill (b. 1956)
