Abstract:
A delayed coking process for making substantially free-flowing coke, preferably shot coke. A coker feedstock, such as a vacuum residuum, is heated in a heating zone to coking temperatures then conducted to a coking zone wherein volatiles are collected overhead and coke is formed. A low molecular weight additive is added to the feedstock prior to it being heated in the heating zone, prior to its being conducted to the coking zone, or both.
