    摘要: Processes for the simultaneous desulfurization and hydroconversion of heavy carbonaceous feeds, including various sulfur-containing heavy petroleum oils, are disclosed. These feeds are contacted with alkali metal hydroxides in a conversion zone, in the presence of added hydrogen, and at elevated temperatures, whereby the feeds are substantially desulfurized, while at the same time significant upgrading of these feedstocks is obtained as demonstrated by decreased Conradson carbon, increased API gravity, and the conversion of a substantial portion of the 1,050.degree. F+ portion of the feedstream. In addition, methods for the regeneration of alkali metal hydroxides from the alkali metal salts produced in the conversion zone are disclosed.

    摘要: A process for hydrocracking hydrocarbon stocks by contacting such stocks under hydrocracking conditions with a nickel oxidetungsten oxide catalyst distended on an ultrastable faujasite base that has been exchanged to incorporate chromium oxide therein. The use of this catalyst allows the refiner to hydrocrack feedstocks that contain large quantities of sulphur and nitrogen compounds. The use of the specially prepared chromium zeolite base also increases the life of the catalyst.

    摘要: Heavy hydrocarbon feed oils such as heavy gas oils, residium, topped crude oils and the like are hydrocracked by mixing hydrogen with the feed oil in the ratio of hydrogen to feed oil in the range from 4000 to 10,000 SCF of hydrogen per barrel of feed oil and contacting this mixture under hydro-treating conditions with a supported micro-spherical catalyst having 5-20 weight per cent tungsten and 0.5 to 5.0 weight per cent rhenium. Increased isoparaffin and aromatic content in the cracked product is obtained.

    摘要: A catalytic slurry hydrorefining process of a hydrocarbonaceous charge stock containing hydrocarbon-insoluble asphaltenes is effected by dissolving in the charge stock an oxyvanadate salt having the following structural formula: (N(R)4)3V0(X)5 wherein ''''X'''' is a cyano, or thiocyano radical, and ''''R'''' is hydrogen, or an alkyl group containing up to 10 carbon atoms. The slurry is formed in situ at hydrorefining conditions with hydrogen containing hydrogen sulfide resulting in colloidally dispersed vanadium sulfide.

    摘要: 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.
