Abstract
Abstract Incorporation of 30-65 percent w of a hydrogenation metal component into a hydrogel which would yield on drying and calcining without the hydrogenation metals a xerogel of a high compacted bulk density (0.8-1.6 g/cc) low pore volume (0.15-0.45 cc/g) alumina results in a catalyst having a very high hydrogenation and denitrification activity. Up to about 10 percent fluoride is added to provide a cracking component. The hydrogenation metal component is selected from the oxides of nickel, molybdenum, tungsten, cobalt and mixtures thereof.

Claim 2
Dependent Claim
21 words
The process of claim 1 wherein the hydrogenation component is 10-18 percent wt nickel oxide and 25-40 percent wt tungsten oxide.
Claim 3
Dependent Claim
21 words
The process of claim 1 wherein the hydrogenation component is 10-18 percent wt nickel oxide and 20-40 percent wt molybdenum oxide.
Claim 4
Dependent Claim
38 words
The process of claim 1 wherein the conversion is substantially hydrodenitrification, the catalyst composite contains from 1-9 percent wt fluoride and the hydrogenation component is selected from the group consisting of the oxides of nickel-tungsten, nickel-molybdenum and cobalt-molybdenum.
