    摘要: A bottoms fraction of fuels hydrocracking which boils above about 600.degree. F. and contains at least 10 wt. % aromatics is converted to a reduced aromatics lube/base stock product over a catalyst comprising a crystalline material which exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams anhydrous crystal at 50 torr and 25.degree. C. and a-hydrogenation-dehydrogenation functionality, preferably palladium, under high pressure conditions sufficient to reduce the aromatics content to about 10 wt. %. The bottoms fraction is dewaxed prior to high pressure hydroprocessing over a catalyst comprising HZSM-5 to reduce the pour point of the fraction to about 20.degree. F. Typically, the bottoms fraction is produced in a moderate pressure fuels hydrocracking process over a bifunctional amorphous catalyst.

    摘要: A process for producing substantially linear hydrocarbons by oligomerizing a lower olefin at elevated temperature and pressure which comprises contacting the lower olefin under oligomerization/polymerization conditions with siliceous acidic ZSM-23 zeolite having Bronsted acid activity; wherein the zeolite has acidic pore activity and wherein the zeolite surface is rendered substantially inactive for acidic reactions. The zeolite surface can be neutralized by a bulky pyridine compound having an effective cross-section larger than the zeolite pore. The preferred deactivating agent is 2,4,6-collidine, which may be applied to the zeolite as a pretreatment or added with olefin feed in a continuous process. The olefin oligomers may be used as alkylating agents to prepare biodegradable alkylbenzenes and alkylphenylsulfonates. A preferred catalyst for this alkylation reaction is dealuminized mordenite.
