    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： There are provided a catalyst, a method for making this catalyst, and a process for using this catalyst in the alkylation of an isoparaffin with an olefin to provide an alkylate. The catalyst may be made from an as-synthesized material which, upon calcination, is capable of generating zeolites designated MCM-22. The as-synthesized material is then combined with a binder material, such as alumina, by an extrusion process. The uncalcined bound material may then be ammonium exchanged, followed by a calcination treatment. The as-synthesized material may also be swollen with a suitable swelling agent, such as a cetyltrimethylammonium compound, prior to the binding process.

    摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst comprising a zeolite sorbing 10 to 40 mg 3-methylpentane at 90.degree. C., 90 torr, per gram dry zeolite in the hydrogen form, e.g., ZSM-22, ZSM-23, or ZSM-35. The treatment over the acidic catalyst 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. The use of the specified zeolite provides greater desulfurization, gasoline selectivity, and octane than obtained using ZSM-5.
