ABSTRACT:
A catalytic composite of improved selectivity and a method of manufacture is disclosed. The catalytic composite is particularly effective with respect to the transalkylation of toluene. The catalytic composite is characterized by a method of preparation which comprises subjecting a mordenite alumina to an aqueous ammoniacal treatment at a pH of at least about 9.5; calcining the resulting mordenite to an aqueous solution containing a boron salt; and calcining the resulting mordenite alumina to provide said catalytic composite.
