Abstract:
A process for the production of lubricating oils from petroleum stocks containing significant quantities of sulfur and lubricating oil components boiling above about 650.degree. F. (343.degree. C.) by subjecting such stocks to a series of steps comprising hydrodesulfurization, fractionation, and solvent extraction. The residual fraction obtained from the fractionation step may be deasphalted prior to solvent extraction.
