Zeolite catalyst and method of manufacture and use thereof

Abstract From the Canadian patent

A method of manufacture providing a catalytic composite of improved activity is disclosed. A zeolite of the mordenite crystal structure with a sodium content of less than about 5 wt. % as Na2o is subjected to an aqueous ammoniacal treatment at a pH of at least about 9.5 and calcined in intimate admixture with a refractory inorganic oxide to form a catalytic composite therewith. Use of the catalyst for transalkylation of alkylaromatic hydrocarbon is also disclosed.
