A synthetic crystalline zeolite is provided characterized by having a composition, in terms of mole ratios of oxides, in the range: 0.9 to 1.1 M 2/n O:Al 2 O 3 :2.5 to 5.1 SiO 2 :xH 2 O wherein M is at least one exchangeable cation, n is the valence of M, and x is 0 to 6, and characterized by having a specified X-ray powder diffraction pattern. The zeolite may be prepared by crystallization from a reaction mixture of KOH (and optionally a minor amount of NaOH), water, a source of silica, and a source of alumina preferably derived from kaolin or halloy...


1. A process for preparing a crystalline zeolite having a composition, in terms of mole ratios of oxides, in the range: ##EQU##0.9 to 1.1 M 2 O:Al 2 O 3 :2.5 to 5.1 SiO 2 :0 to 6 H 2 O where M is K or a mixture of K and Na, where Na is no more than 30 mole percent of the mixture, and characterized by having an X-ray powder diffraction pattern essentially identical to that given in Table IV which is characteristic of zeolite L, which comprises: (a) preparing a reaction mixture comprising water, a source of silica, metakaolin, KOH and up to about 30 mo...
