    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: This invention relates to a method for calcining without structural alteration crystalline [metallo]aluminophosphate compositions, e.g, those comprising pores which are formed by 18-membered rings. The method comprises contacting the dried composition with an inert gas at high flow rates while heating said composition to calcining temperature at a heating rate no greater than 10.degree. C./minute. Thereafter the composition is contacted at calcining temperature with an oxygen-containing gas at high flow rates.
