Abstract
Described are catalyst mixtures comprising a HAMS-1B crystalline borosilicate molecular sieve incorporated into an inorganic matrix component and a molybdenum on silica component. These mixtures when used to isomerize unextracted xylene streams containing ethylbenzene to mixtures rich in paraxylene demonstrate improved paraffins and naphthenes conversion to light hydrocarbons and convert most of the ethylbenzene by a hydrodeethylation mechanism to benzene and ethane.
