ABSTRACT:
Zeolite L is made from an aqueous precursor mixture that contains from 0.1 to about 10% by weight of an amorphous aluminosilicate seeding gel which does not contain zeolite L. Using this mixture zeolite L can be made in a much shorter time than with a synthesis mixture without the seeding gel, and with substantially no zeolite T impurity. When made at temperatures below about 120.degree. C the zeolite. L has a disk-shaped morphology which is substantially free of zeolite T (offretite type).
