    Abstract: 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 ANGSTROM 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 DEG C. The crystalline material is characterized by an X-ray diffraction pattern with at least one d-spacing greater than 18 ANGSTROM and in a particularly preferred form, a hexagonal arrangement of pores of at least 13 ANGSTROM diameter which can be indexed with a d100 value greater than 18 ANGSTROM . 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.

    Abstract: A hydrogenation process for reducing the unsaturation of lubricants uses a catalyst which is based on an ultra-large pore crystalline material. The crystalline material has pores of at least 1.3 nm (13 ANGSTROM ) diameter arranged in a uniform manner and exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than 15 grams benzene/100 grams (6.7 kPa/50 torr and 25 DEG C). A preferred form of the catalyst has a hexagonal structure which exhibits a hexagonal electron diffraction pattern that can be indexed with a d100 value greater than 1.8 nm (18 ANGSTROM ). The hydrogenation catalysts based on these materials are capable of reducing the unsaturation in poly alpha olefin lubricants to a low level.

    Abstract: Paraffins, especially light paraffins in the C4-C8 range, are isomerized to iso-paraffins over an isomerization catalyst comprising a noble metal such as platinum on a support material comprising an inorganic, non-layered, porous, crystalline phase aluminosilicate material which exhibits, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than 18 Å and a benzene adsorption capacity greater than about 15 grams benzene per 100 grams at 50 torr and 25 °C. In its preferred form, the support material has a uniform, hexagonal arrangement of pores with diameters of at least about 13 Å and a hexagonal electron diffraction pattern that can be indexed with a d100 value greater than about 18 Å which corresponds to at least one peak in the X-ray diffraction pattern.
