Title:
潤滑剤水素化分解方法
Document Type and Number:
Japanese Patent JP3677039
Kind Code:
B2
Abstract:
A bottoms fraction of fuels hydrocracking which boils above about 600 DEG 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 DEG 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 DEG F. Typically, the bottoms fraction is produced in a moderate pressure fuels hydrocracking process over a bifunctional amorphous catalyst.
