Abstract
An improved catalyst is disclosed for the conversion of aromatic hydrocarbons which comprises a Group VIII metal, lead, a pentasil zeolite, and an inorganic oxide binder, wherein 80-100% of the Group VIII metal and 60-100% of the lead are contained on the binder. An alkylaromatic isomerization process also is disclosed which is particularly effective for the conversion of ethylbenzene without substantial loss of xylenes.
