Abstract A hydrocarbon hydroprocess utilizing a catalytic composite of a porous carrier material, a Group VIII noble metal component and a lead component, in which process there is effected a chemical consumption of hydrogen. A specific example of one such catalyst is a composite of a crystalline aluminosilicate, a platinum component and a lead component, for utilization in a hydrocracking process. Other hydrocarbon hydroprocesses are directed toward the hydrogenation of aromatic nuclei, the ringopening of cyclic hydrocarbons, desulfurization, denitrification, hydrogenation, etc. The catalyst contains 0.01 percent to about 2.0 percent by weight of the noble metal component, and the atomic ratio of lead to noble metal is in the range of 0.05:1 to 0.9:1.
The process of claim 1 further characterized in that said Group VIII noble metal is platinum or palladium.
Claim 2
Dependent Claim
22 words
The process of claim 2 further characterized in that said catalytic composite is reduced and sulfided prior to contacting said charge stock.
Claim 3
Dependent Claim
31 words
The process of claim 1 further characterized in that said catalytic composite contains from about 0.1 percent to about 1.5 percent by weight of a halogen component, on an elemental basis.
Claim 4
Dependent Claim
16 words
The process of claim 2 further characterized in that said carrier material is a crystalline aluminosilicate.
Claim 5
Dependent Claim
18 words
The process of claim 2 further characterized in that said carrier material is an amorphous refractory inorganic oxide.
Claim 6
Dependent Claim
