AMS-1B crystalline borosilicate molecular sieve-based catalyst compositions and process for xylene isomerization
Patent
·
OSTI ID:6868824
A process is described for isomerizing a xylene feed containing a minor amount of ethylbenzene comprising contacting the xylene with a catalyst composition comprising a HAMS-1B crystalline borosilicate molecular sieve incorporated into an inorganic matrix. The composition is impregnated with a suitable phosphorus compound and is subsequently heated to substantially convert the compound to the oxide form.
