Abstract: A high-viscosity-index mineral lubricating oil is produced by treating, for instance, a deasphalted residuum or a raw, heavy lubricating distillate oil in a two-stage process. The feedstock is first catalytically hydrocracked, then catalytically hydrogenated and can be fractionated and dewaxed to produce a finished product. Catalysts such as nickel-tungstate on boriaalumina and nickel-molybdate on alumina are employed in the two stages, respectively. The catalysts are preferably used in sulfided form.

Abstract: Technical grade white mineral oil is produced by a series of steps including treating a mineral lubricating oil distillate with hydrogen in the presence of a sulfur-resistant catalyst (e.g., nickel molybdate on alumina) under hydrorefining conditions. The hydrogenated oil is hydroisomerized and hydrocracked by contact with hydrogen in the presence of a silica-alumina and crystalline-aluminosilicate-containing catalyst having about 0.1 to 5 weight percent of a platinum group metal. The resulting product is further contacted with hydrogen under aromatic saturation conditions in the presence of a platinum group metal-containing hydrogenation catalyst (e.g., platinum on alumina).
