摘要:
A process for upgrading a heavy hydrocarbonaceous oil is provided in which the oil is hydrorefined, heat-treated and hydrocracked to increase the selectivity of the hydrocracked product to components boiling in the range of 350.degree. to 675.degree. F.
摘要:
A fluid coking process is provided in which the fluidizing and stripping gas is introduced as a plurality of streams in the proximity of flow deflecting means positioned in the stripping portion of the coking reactor such as to provide a specified superficial gas velocity in the stripping portion.
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.
