Zusammenfassung:	PCT No. PCT/US90/06306 Sec. 371 Date Jun. 30, 1992 Sec. 102(e) Date Jun. 30, 1992 PCT Filed Oct. 30, 1990 PCT Pub. No. WO91/06367 PCT Pub. Date May 16, 1991.Potassium zeolites of type L in which the crystals are very flat cylinders of "hockeypuck" or "coin" shape may be prepared by adjusting the K2O/SiO2 and SiO2/Al2O3 ratio and including in the mixture from which the zeolite is crystallized a small amount of divalent cation such as magnesium or barium. The resulting zeolite has a short channel length and is particularly useful as a base for aromatization catalysis.
