Abstract
Abstract A process for the catalytic reforming of a naphtha fraction is disclosed. A naphtha fraction and hydrogen are commingled and passed in contact with a germanium-promoted platinum group metal catalyst at reforming conditions. The catalyst is characterized by a novel method of manufacture affording an improved reforming process. The catalyst preparation comprises impregnating a carrier material with a non-aqueous solution of a platinum group metal compound and a halo-substituted germane, the impregnated carrier material being subsequently dried and calcined.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A process for the catalytic reforming of a naphtha fraction which comprises passing said naphtha fraction and hydrogen in contact with a germanium-promoted platinum group metal catalyst at reforming conditions, said catalyst having been prepared by impregnating a porous high surface area carrier material with a non-aqueous solution of a platinum group metal compound and a halo-substituted germane containing less than four halo substituents in an amount to provide a final catalyst containing from about 0.05 to about 1.0 wt. % platinum group metal and from about 0.05 to about 1.0 wt. % germanium, and drying and calcining the thus impregnated carrier materials, said platinum group metal compound being selected from the group consisting of chloroplatinic acid, platinum chloride, ammonium chloroplatinate, dinitrodiaminoplatinum, palladium chloride, chloropalladic acid, rhodium chloride, ruthenium chloride, ruthenium oxide, osmium chloride and iridium chloride.
