Abstract

A process for the production of needle-grade coke having a low coefficient of thermal expansion (CTE) value involves coking a petroleum feedstock in a coking drum at temperature below the threshold temperature where CTE values for the coke rapidly increase for a time sufficient to obtain a relatively low CTE coke. The petroleum feedstock can be decanted oil or heavy cycle oil. The threshold temperature can be from about 400 DEG C to 600 DEG C. A heated vapor stream is introduced into the drum to maintain the coke at a temperature sufficient for coking but below the threshold temperature.
