ABSTRACT:
Agglomerated crystalline zeolites are deagglomerated by treating the zeolite following crystallization. At a point where crystallization is complete, a basic solution is added and/or the temperature of the reaction mass is increased by between 50.degree. and 100.degree. F. Alternatively, the crystalline zeolite is recovered and thereafter treated with a basic solution.
