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:
“The old priest Peter Gilligan
Was weary night and day;
For half his flock were in their beds,
Or under green sods lay.”
—William Butler Yeats (1865–1939)
“Name me, if you can, a better feeling than the one you get when you’ve half a bottle of Chivas in the bag with a gram of coke up your nose and a teenage lovely pulling off her tube top in the next seat over while you’re doing a hundred miles an hour in a suburban side street.”
—P.J. (Patrick Jake)
