Hydrotreating catalyst and process

Claim 1

A hydrotreating process which comprises contacting a hydrocarbon feed containing substantial amounts of materials boiling above 200° F. and selected from the group consisting of petroleum distillates, solvent-deasphalted petroleum residua, shale oils and coal tar distillates, in a reaction zone with hydrogen and a catalyst, at hydrotreating conditions including a temperature in the range 400° to 950° F., a pressure in the range 800 to 3500 psig, a liquid hourly space velocity in the range 0.1 to 5.0, and a total hydrogen supply rate of 200 to 20,000 SCF of hydrogen per barrel of feedstock, and recovering hydrotreated products from said reaction zone, said catalyst being a composite comprising A. a gel matrix comprising based on the entire content of said gel matrix: a. less than 15 weight percent silica, b. alumina, in an amount providing an alumina-to-silica weight ratio of 50/50 to 100/0, c. nickel or cobalt, or the combination thereof, in the form of metal, oxide, sulfide or any combination thereof, in an amount of 1 to 10 weight percent of said matrix, calculated as metal, d. molybdenum or tungsten, or the combination thereof, in the form of metal oxide, sulfide or any combination thereof, in an amount of 5 to 30 weight percent of said matrix, calculated as metal; B. a crystalline zeolitic molecular sieve containing less than 5 weight percent sodium and containing ions selected from Mn, rare earths of atomic numbers 58-71, and alkaline earths Mg, Ca, Sr and Ba, said sieve further being in the form of particles, said particles being dispersed through said gel matrix; said catalyst having an average pore diameter below 100 Angstroms and a surface area above 200 square meters per gram.
