Abstract
Hydroprocessing catalysts of high metal content and surface area are based on a support material comprising a non-layered, 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. and may be characterized by an X-ray diffraction pattern with at least one d-spacing greater than about 18 .ANG.. In a particularly preferred form, the crystalline material has a hexagonal arrangement of pores of at least 13 .ANG. diameter which has an electron diffraction pattern with one line at a d.sub.100 value greater than about 18 .ANG.. The catalysts based on these materials are capable of accommodating high metal loadings while retaining a high surface area with high pore volume and low density. Because of the high surface area of the support material, the metals may be incorporated by simple impregnation in a single step. The catalysts are particularly useful for process applications requiring high hydrogenation functionality and acidic functionality and therefore are useful in…
