Selective catalytic conversion of a C9 aromatic feedstock containing substantial amounts of ethyl subsituted aromatic components to a product rich in toluene and/or xylenes

摘要

This invention is an improved process for the conversion of a C9 mixed alkyl aromatic feedstream containing ethyl substituted aromatics to a product rich in toluenes and/or xylenes via catalytic transalkylation/disproportionation using a palladium loaded moderately, dealuminated mordenite catalyst in the presence of added hydrogen and benzene.
