Abstract
Type Y zeolite is prepared using a minimum excess of reactants by a method wherein required sodium hydroxide, silica, alumina and water reactants are combined in multi-stage procedure to obtain a uniform fluid reaction slurry. The procedure permits the efficient commercial production of high quality type Y zeolite and minimizes the formation of excess silicate containing by-product effluent.
