Abstract
A process for providing distillate products which are substantially sulfur free, which process comprises subjecting a distillate stream to conventional hydrodesulfurization conditions including a catalyst comprised of a Group VI metal and at least one Group VIII metal on a refractory support. The hydrodesulfurized stream is then treated with a solid adsorbent material capable of adsorbing beta and di-beta-substituted dibenzothiophene sulfur compounds.
