摘要： The present invention relates to provide new crystalline zeolite catalyst (ZKU-catalyst) having the superior catalytic activity and selectivity and the long period of the catalytic life.One of the method of said catalyst (ZKU-2 catalyst) lies in crystallizing the starting zeolite preparation in the presence of the crystallization conditioning agent of crystallization of tetraalkyl (methyl or ethyl or combination thereof) ammonium cation.Another method of said catalyst (ZKU-3, 4 catalysts) lies in crystallizing the starting zeolite preparation in the presence of both said conditioning agent of crystallization and the substance capable of forming the seed and/or the skelton of crystal. The ZKU-3 catalyst is manufactured using the seed of crystal, while the ZKU-4 catalyst is manufactured using the seed and the skelton of crystal.The seed of crystal is useful for the promoter of the crystallization rate and the improvement of the catalytic activity, the skelton of crystal is useful for so-called "skelton" which is of use for the improvement of the mechanical strength, the dimentional stability and the conditioning of the pore structure of crystal in the molded catalyst and also for the improvement of uniformly dispersing the components of the catalytic composition.The characteristic feature of the ZKU-2, 3 and 4 catalysts of the present invention has been compared with that of the ZSM-34 catalyst.

摘要： The present invention relates to a new method for supporting a metal and/or a metal oxide on a crystalline aluminosilicate zeolite. The resulting products are useful as catalysts and are designated ZKU-5, ZKU-6 and ZKU-7 (Zeolite Kyoto University catalyst). These catalysts display superior catalytic activity and selectivity and have a longer life than catalysts of the prior art.One method of the invention involves crystallizing a zeolite composition in the presence of both a conditioning agent and a crystal seed supporting the metal and/or metal oxide, the latter providing a nucleus for crystallization. The conditioning agent comprises the lower analogs of a tetraalkyl ammonium cation. The resulting crystal can support one or more metals or metal oxides or a mixture thereof.The disclosure compares the catalysts of the invention with a known, prior art catalyst, namely ZSM-34.
