    • A lube hydrocracking process uses a catalyst which is based on an ultra-large pore crystalline material. The crystalline material exhibits unusually large pores of at least 13 .ANG. diameter and a high sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C. The crystalline material is characterized by an X-ray diffraction pattern with at least one d-spacing greater than about 18 .ANG. and in a particularly preferred form, a hexagonal arrangement of pores of at least 13 .ANG. diameter which can be indexed with a d.sub.100 value greater than about 18 .ANG.. 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.

    • Dispersed Active Metal catalyst for hydrogenation reactions is produced by treating a substantially catalytically inactive metal particulate with a solution capable of oxidizing the metal particulate and comprising of at least one compound of a hydrogenation catalyst metal thereby forming a layer of at least one of hydroxides and oxides thereon. The metal particulate is activated by treatment with a hydrogen-containing gas at elevated temperatures to form a porous layer of Dispersed Active Metal catalyst. Preferably, the treated metal particulate is dried prior to activation, and also preferably calcined in an oxidant-containing atmosphere prior to activation. The treatment solution may advantageously contain a compound of at least one promoter metal for the added catalyst metal. The porosity of the layer provides enhanced catalyst activity as well as improved methane selectivity in the Fischer-Tropsch process.
    • 用于氢化反应的分散活性金属催化剂通过用能够氧化金属颗粒并且包含至少一种氢化催化剂金属的化合物的溶液处理基本上催化惰性的金属颗粒而产生,从而形成氢氧化物和氧化物中的至少一种的层 上。 通过在高温下用含氢气体处理来活化金属颗粒以形成分散活性金属催化剂的多孔层。 优选地,处理的金属颗粒在活化之前被干燥,并且还优选在活化之前在含氧化剂的气氛中煅烧。 处理溶液可以有利地含有用于加入的催化剂金属的至少一种助催化剂金属的化合物。 该层的孔隙率提高了催化剂活性以及在费 - 托工艺中提高的甲烷选择性。
