Abstract
A high crystalline coke can be prepared by heat-soaking a petroleum feedstock in the presence of added dissolved sulfur, heating to effect controlled thermal cracking thereof, separating non-crystalline substances as pitch, recovering a heavy cokable residue from the pitch free feed, and subjecting the residue to delayed coking.
