There is disclosed a process for isomerizing alkylated benzenes having from 3-10 carbon atoms and methyl or ethyl alkyl substituents. The reaction is conducted in the presence of molecular hydrogen and a catalyst having a platinum group metal, especially platinum, and rhenium promoters on a porous, solid oxide, acidic support. The support can be a mixture of a low acidic material such as alumina, and a higher acidic material such as silica-alumina or crystalline aluminosilicate. The catalyst promoters are preferably supported on the low acidity base component.
