ZEOLITE L |
摘要 |
Potassium zeolites of type L in which the crystals are very flat cylinders of "h ockeypuck" 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. |
