A commonly used term for a primary
carbonization product (
green or
raw coke) from high-boiling hydrocarbon fractions (heavy residues of petroleum or coal processing)
produced by the
delayed coking process.
Note:
Delayed
coke has, with only a few exceptions, a better graphitizability than
cokes produced by other
coking processes even if the same feedstock is used. Delayed
coke contains a
mass fraction of volatile matter between 4 and 15 wt% which can be released during heat treatment.
