    摘要: A process for producing high quality lubricants by hydrocracking a high boiling hydrocarbon feed in the presence of hydrogen and a bifunctional hydrocracking catalyst based on an ultra-large pore crystalline material. The crystalline material exhibits unusually large pores of at least 13 Å diameter and a high sorption capacity demonstrated by its benzene adsorption capacity of greater than 15 grams benzene/100 grams at 6.7 kPa (50 Torr) and 25 °C. The crystalline material is characterized by an X-ray diffraction pattern with at least one d-spacing greater than 18 Å and in a particularly preferred form, a hexagonal arrangement of pores of at least 13 Å diameter which can be indexed with a d100 value greater than 18 Å. The hydrocracking catalysts based on these materials are capable of producing hydrocracked lube products of good viscosity index in high yields without the use of fluorine or other promoters. Petroleum waxes may be used as the feed and is hydrocracked and hydroisomerized to form the lube products.

    摘要: This invention discloses a process for producing a high Viscosity Index lubricant having a viscosity of at least 125 from a waxy hydrocarbon feed having a wax content of at least 40 wt.%. The process comprises catalytically dewaxing waxy paraffins present in the feed primarily by isomerization, in the presence of hydrogen and in the presence of a low acidity large pore zeolite molecular sieve having a crystal size of less than 0.1 micron, an alpha value of not more than 30 and containing a noble metal hydrogenation component. The large pore zeolite is preferably zeolite beta loaded with 0.3 to 2 wt.% Pt. The feed may be hydrocracked prior to dewaxing with the large pore zeolite. The effluent of the process may also be further dewaxed by either solvent or catalytic means in order to achieve target pour point.
