ISOMERIZATION OF MONOCYCLIC ALKYL AROMATIC HYDROCARBONS

C-8 mixtures are isomerized in the vapor phase over ZSM-5 acting catalyst in the presence of a xyleneloss-reducing diluent comprising toluene plus C-9+ recycle. The process is conducted in the presence of hydrogen and the catalyst includes a non-noble metal component.
