Abstract
Abstract Disclosed is a catalyst essentially free of platinum, comprising from about 0.1 to about 2 weight percent rhenium and about 0.1 to about 2 weight percent gallium supported on a solid inorganic refractory oxide. A hydrocarbon conversion process, such as catalytic reforming, is also disclosed wherein the process contacts the above described catalyst with a hydrocarbon stream boiling in the range of about 70° F. to about 500° F. and hydrogen. A two-step process is also disclosed wherein a platinum catalyst is first contacted with a hydrocarbon stream to achieve a partial conversion followed by contacting the above described catalyst to achieve further conversion.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
42 words
A catalytic composition for the reforming of petroleum hydrocarbons, which catalytic composition consists of from about 0.1 to about 2 weight percent rhenium and from about 0.1 to about 2 weight percent gallium supported on a solid porous refractory inorganic oxide support.
Claim 2
Dependent Claim
42 words
A catalytic composition for the reforming of petroleum hydrocarbons, which catalytic composition consists of from about 0.1 to about 2 weight percent rhenium and from about 0.1 to about 2 weight percent gallium supported on a solid porous refractory inorganic oxide support.
Claim 3
Dependent Claim
30 words
The composition of claim 1 wherein said catalytic composition consists of from about 0.2 to about 0.8 weight percent rhenium and from about 0.2 to about 0.8 weight percent gallium.
Claim 4
Dependent Claim
33 words
The composition of claim 1 wherein the preparation of said catalytic composition comprises impregnating the solid porous refractory inorganic oxide support with soluble compounds of rhenium and gallium followed by drying and calcining.
Claim 5
Dependent Claim
15 words
The composition of claim 1 wherein the refractory inorganic oxide is a halogen-free inorganic oxide.
Claim 6
Dependent Claim
19 words
The composition of claim 1 wherein the rhenium and gallium are characterized as metal, oxide, sulfide, or mixtures thereof.
Claim 7
Dependent Claim
22 words
The composition of claim 1 wherein said solid porous refractory inorganic oxide support is catalytically active alumina, silica-alumina, silica-magnesia, titania-alumina or zinc-oxide-alumina.
Claim 8
Dependent Claim
16 words
The composition of claim 4 wherein said solid porous refractory inorganic oxide support is gamma alumina.
Claim 9
Dependent Claim
21 words
The composition of claim 7 comprising about 0.5 weight percent rhenium and about 0.5 weight percent gallium supported on gamma alumina.
Claim 10
Dependent Claim
30 words
The composition of claim 1 wherein said solid porous refractory inorganic oxide support is mordenite, said mordenite having a silica-to-alumina ratio within the range of about 6 to about 100.
Claim 11
Dependent Claim
59 words
The composition of claim 7 wherein preparation of the catalytic support component of said composition comprises blending finely-divided mordenite-type alumino-silicate material into a sol or gel of said refractory inorganic oxide to form a blend, gelling said blend by adding a solution of a suitable inorganic ammonium-affording compound, and drying and calcining the gel to form a calcined material.
Claim 12
Dependent Claim
53 words
The composition of claim 10 wherein said refractory inorganic oxide is a catalytically active alumina and said mordenite is suspended in and distributed throughout a matrix of said alumina, said mordenite being present in an amount of about 1 weight percent to about 50 weight percent, based on the weight of said support.
