Isomerization catalyst and process for production thereof

Abstract

A process for converting linear aliphatic olefins into branched-chain aliphatic olefins, by contacting said linear aliphatic olefins with a comprising an active alumina carrier and fluorine and chlorine supported thereon, the amounts of fluorine and chlorine supported being 0.2 to 2.0% by weight, and 0.2 to 4.0% by weight, respectively, based on the total weight of the catalyst composition. The aforesaid isomerization catalyst can be produced by contacting an active alumina carrier with at least one halogenated hydrocarbon containing fluorine and chlorine in the molecule at a temperature of 200.degree. to 500.degree. C.
