摘要
A raffinate product of residual oil solvent extraction is upgraded in a fluid zeolite catalyst cracking operation in the presence of one or more low molecular weight carbon-hydrogen fragment contributors. Gas oil products of atmospheric and vacuum distillation may be simultaneously converted by admixture with the raffinate charge. In addition the process is enhanced by the addition of straight run naphtha product of distillation with the raffinate charge.
