ABSTRACT:
An improved process for the isomerization of non-equilibrium C.sub.8 aromatics is presented which utilizes a novel catalytic composition. This catalyst comprises phosphorus-containing alumina, a gallium component, and crystalline aluminosilicate zeolite having a silica to alumina ratio of at least 12. The isomerization process has a particular utility for the conversion of ethylbenzene without the deleterious loss of xylene.
