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.
Delayed @C01142-1@ has, with only a few exceptions, a better graphitizability than @C01142-2@ produced by other @C01144@ processes even if the same feedstock is used. Delayed @C01142-1@ contains a @M03722@ of volatile matter between 4 and 15 wt% which can be released during heat treatment.
