Abstract
Abstract The process comprises contacting a mineral lubricating oil distillate in a first reaction zone with a sulfactive hydrogenation catalyst in the presence of hydrogen and under hydrogenation and desulfurization conditions to produce a desulfurized product and contacting said desulfurized product in a second reaction zone with the catalytic composition of the invention in the presence of hydrogen and under selected conditions. The catalytic composition comprises a Group VIII noble metal deposited upon a large-pore-diameter alumina.
