    摘要: The invention relates to framework gallium containing ultrastable Y having a framework (silica:alumina+gallium oxide) SiO.sub.2 /(Al.sub.2 O.sub.3 +Ga.sub.2 O.sub.3) mole ratio of 18:1 which contains at least 2.2% framework gallium. Moreover, the invention includes use of the framework gallium containing ultrastable Y in hydrocarbon conversion processes, such as reforming, catalytic cracking and aromatization.

    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.
