Abstract
An improved catalyst for the isomerization of non-equilibrium C.sub.8 aromatics is presented which utilizes a novel catalytic composition. This catalyst comprises a Group VIII metal component, a bismuth component, and crystalline aluminosilicate zeolite having a silica to alumina ratio of at least 12. An isomerization process is also disclosed which has a particular utility for the conversion of ethylbenzene without the deleterious loss of xylene.
