Abstract
A delayed coking process in which the overhead vapors from a delayed coking drum are separated into light hydrocarbon products and a gas oil, and in which the gas oil is hydrotreated after being separated from the light hydrocarbon products. The hydrotreated gas oil is then combined with coker feedstock and fed to the coking drum. The process produces a coke capable of producing a graphitized product having a lower longitudinal coefficient of thermal expansion than that of the coke product produced from the same feedstock by the same process but without the hydrotreating step.
