    摘要: The present invention relates to a process for producing crystalline aluminosilicates having in the hydrogen form an X-ray diffraction pattern substantially as set forth in Table 1 of this specification and the following composition in terms of the mole ratios of the oxides:0.9=0.2 M.sub.2 /.sub.n O:Al.sub.2 O.sub.3 :xSiO.sub.2 :yH.sub.2 O:zNH.sub.3wherein M is at least one cation having a valence n, x is at least 10, y/x is from 0 to 5 and z/x is 0-5. The process comprises mixing a source of silica, a source of alumina, a source of alkali metal(s), water and ammonia until a homogeneous gel is formed and crystallizing the gel at a temperature above 70.degree. C. for a period of at least 2 hours. The crystalline aluminosilicate thus produced can be used, whether or not impregnated and/or ion-exchanged, as catalysts for any one of the following reactions: alkylation, dealkylation, dehydrocyclodimerization, aromatization, transalkylation, isomerization, dehydrogenation, hydrogenation, cracking, cyclization, oligomerization, polymerization, and dehydration reactions.
