    摘要: A coking process is provided in which a stream of heavy oil product, which typically is recycled to the coking zone, is first subjected to solvent separation using coker naphtha as solvent to separate the heavy oil into a high Conradson carbon content product comprising a minor portion of the coker naphtha and a lower Conradson carbon content product comprising a major portion of the coker naphtha and, thereafter, recovering the lower Conradson carbon content product and recycling the high Conradson content product, including the minor portion of coker naphtha, to the coking zone.
