摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment in a second step over a a first catalyst zone comprising a large pore size zeolite material and a second catalyst zone comprising an intermediate pore size material. Preferably, the large pore size material is zeolite beta and the intermediate pore size material is ZSM-5. The treatment in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

摘要： A process is provided for producing low sulfur gasoline of relatively high octane number from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst comprising crystals having the structure of ZSM-12. The treatment over the acidic catalyst comprising ZSM-12 in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

摘要： A moderate pressure hydrocracking process in which a highly aromatic, substantially dealkylated feedstock is processed to high octane gasoline and low sulfur distillate by hydrocracking over a catalyst, preferably comprising ultrastable Y and a Group VIII metal and a Group VI metal, in which the amount of the Group VIII metal content is incorporated at specified proportion into the framework aluminum content of the ultrastable Y component. The feedstock which is preferably a light cycle oil has an aromatic content of at least 50, usually at least 60 percent, and an API gravity not more than 25. The hydrocracking typically operates at 400-1000 psig at moderate to high conversion levels to maximize the production of monocyclic aromatics which provide the requisite octane value to the product gasoline. The distillate products from the hydrocracker are reduced in their sulfur content.

摘要： A hydrocracking process employing a hydrocracking catalyst based on zeolite beta together with a metal hydrogenation/dehydrogenation component recycles the unconverted, hydrocracked bottoms fraction to the hydrocracking step for improvements in distillate selectivity and denitrogenation without loss of catalyst activity while improving dewaxing of the unconverted bottoms fraction. The process typically operates at low to moderate hydrogen pressures up to 1500 psig (10445 kPa) with low hydrogen consumptions typically below 800 SCF/Bbl (142 n.l.l..sup.-1). Denitrogenation is notably high at 90 weight percent or higher.

摘要： Lubricating oil stocks produced by methods such as catalytic dewaxing or hydrocracking, comprising hydroprocesses, are stabilized against oxidation by the addition of hydrogen sulfide to the hydroprocessing hydrogen-containing feed using hydroprocess effluent as a source of said hydrogen-containing feed. The H.sub.2 S present in the hydrogen-containing feed saturates olefins that contribute to oxidation instability and restores antioxidant sulfur compounds such as thiols to the lube stock.

摘要： An improved hydrotreating catalyst, and a process for using thereof, comprises a conventional Group VIA and Group VIIIA metal oxide or metal sulfide, deposited on an inorganic refractory support and about 0.1% by weight to about 7% by weight of the catalyst of a promoter comprising a halogenated metal selected from the Group consisting of halogenated metals of Group IB, IIB, IIIB, titanium and tin. The presence of the promoter results in greater degree of desulfurization and in CCR reduction of hydrocarbon feedstocks, especially highly aromatic petroleum residue and synthetically-derived hydrocarbons, e.g., coal liquids.
