Abstract
A catalytic composite of improved activity and a method of manufacture is disclosed. The catalytic composite is particularly effective with respect to the transalkylation of toluene. The catalytic composite comprises a zeolite of the mordenite crystal structure in from about a 1:3 to about a 3:1 weight ratio with a refractory inorganic oxide. The catalytic composite is characterized by a method of preparation which comprises subjecting zeolite of the mordenite crystal structure, with a sodium content of less than about 5 wt. % as Na.sub.2 O, to an aqueous ammoniacal treatment at a pH of at least about 9.5 in admixture with a substantially acid anion-free refractory inorganic oxide.
