ABSTRACT:
An improved catalyst composition for isomerizing xylene containing a minor amount of ethylbenzene comprising a HAMS-1B crystalline borosilicate molecular sieve incorporated into an inorganic matrix impregnated with a small amount of a phosphorus compound. The catalyst composition when contacted with an ethylbenzene containing xylene under isomerization conditions results in a greater yield of paraxylene and a conversion of ethylbenzene to more useful products.
