Abstract
Abstract A process for hydrotreating (hydroprocessing) hydrocarbons and mixtures of hydrocarbons utilizing a catalytic composite of a porous carrier material, a platinum or palladium component, a rhodium component and a tin 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, a rhodium component and a tin component, for utilization in a hydrocracking process. Other hydrocarbon hydroprocesses are directed toward the hydrogenation of aromatic nuclei, the ring-opening of cyclic hydrocarbons, desulfurization, denitrification, hydrogenation, etc.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
70 words
A process for hydrogenating a coke-forming hydrocarbon distillate containing di-olefinic and mono-olefinic hydrocarbons, and aromatics, which process comprises reacting said distillate with hydrogen, at a temperature below about 500° F., in contact with a catalytic composite of an alumina-containing refractory inorganic oxide, a platinum or palladium component, a rhodium component, a tin component and an alkali metal component, and recovering an aromatic/mono-olefinic hydrocarbon concentrate substantially free from conjugated di-olefinic hydrocarbons.
Claim 2
Dependent Claim
70 words
A process for hydrogenating a coke-forming hydrocarbon distillate containing di-olefinic and mono-olefinic hydrocarbons, and aromatics, which process comprises reacting said distillate with hydrogen, at a temperature below about 500° F., in contact with a catalytic composite of an alumina-containing refractory inorganic oxide, a platinum or palladium component, a rhodium component, a tin component and an alkali metal component, and recovering an aromatic/mono-olefinic hydrocarbon concentrate substantially free from conjugated di-olefinic hydrocarbons.
Claim 3
Dependent Claim
16 words
The process of claim 1 further characterized in that said carrier material is a crystalline aluminosilicate.
Claim 4
Dependent Claim
53 words
The processs of claim 1 further characterized in that said catalytic composite contains from 0.01% to about 2% by weight of said platinum or palladium component, from 0.01% to about 2% by weight of said rhodium component and from 0.01% to about 5% by weight of said tin component, on an elemental basis.
