ABSTRACT:
Zeolite L is prepared in a process employing a mother liquor recycle by adjusting the alkalinity of the crystallization gel containing the mother liquor to suppress zeolite W formation and optionally heat treating the mother liquor prior to recycle to remove zeolite W nuclei and/or crystallites. The technique is especially suitable for the formation of zeolite L with cylindrical morphology from a crystallization gel comprising (in mole ratios of oxides):
