Abstract

Abstract Method for the preparation of isomerization catalysts which comprises supporting on crystalline aluminosilicate with openings of 6-15A. 0.01-5% by weight of palladium or platinum as calculated in terms of the metal by a conventional procedure and then contacting the alumino-silicate with one or more halogenated hydrocarbons wherein the halogen is fluorine and/or chlorine at a temperature from 0* to 350*C. to make a halogen content of 0.0120 percent by weight, and process for the isomerization of hydrocarbons which comprises contacting straight or less branched hydrocarbons with said catalyst at a temperature from 15* to 400*C. in the presence of a hydrogen-containing gas to produce more highly branched hydrocarbons.

Process for the isomerization of hydrocarbons which comprises contacting straight or less branched hydrocarbons with a catalyst at a temperature from 15* to 400*C. in the presence of a hydrogen-containing gas to produce more highly branched hydrocarbons, said catalyst being prepared by contacting crystalline aluminosilicate having openings of 6-15A. on which 0.01-5 percent by weight of a member selected from the group consisting of palladium and platinum as calculated in terms of the metal is supported with at least one halogenated hydrocarbons having from one to six carbon atoms wherein the halogen is a member selected from the group consisting of fluorine and chlorine at a temperature from 0* to 350*C. to make said aluminosilicate have a halogen content of 0.01-20 percent by weight.
