    • 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.
    • 本发明涉及提供具有优异的催化活性和选择性以及长期催化寿命的新型结晶沸石催化剂(ZKU-催化剂)。 所述催化剂(ZKU-2催化剂)的方法之一在于在四烷基(甲基或乙基或其组合)铵阳离子结晶的结晶调节剂存在下使起始沸石制剂结晶。 所述催化剂(ZKU-3,4催化剂)的另一种方法在于在所述结晶调理剂和能够形成晶种的物质和/或晶体的晶体存在下,使起始沸石制剂结晶。 ZKU-3催化剂使用晶体晶种制造,而ZKU-4催化剂使用晶种和晶体晶体制造。 晶体种子对于结晶速率的促进剂和催化活性的提高是有用的,晶体的碳化硅可用于所谓的“skelton”,其用于改善机械强度,尺寸稳定性和 调节成型催化剂中晶体的孔结构,以及改进均匀分散催化剂组合物的组分。 本发明的ZKU-2,3和4催化剂的特征与ZSM-34催化剂的特征进行了比较。

    • A compound oxide X.sub.1 having the oxide composition CuO-ZnO-Cr.sub.2 O.sub.3 -Al.sub.2 O.sub.3 is physically admixed with a compound oxide X.sub.2 prepared by impregnating .gamma.-Al.sub.2 O.sub.3 with La(NO.sub.3).sub.3 and firing the same, to give a CuO-ZnO-Cr.sub.2 O.sub.3 -Al.sub.2 O.sub.3 -La.sub.2 O.sub.3 -based compound oxide with an La.sub.2 O.sub.3 addition level of 4% by weight. This compound oxide is reduced and packed into a reactor and a mixed gas composed of CO.sub.2 and H.sub.2 in a mole ratio of 1:3 is fed to the reactor, whereby methanol is obtained in high yield. The total conversion of CO.sub.2 amounts to 31.0%, the conversion to methanol being 22.9% (selectivity toward methanol 73.9%). When the pressure is 80 atmospheres, the conversion of CO.sub.2 amounts to 39%, the conversion to methanol being 29%.
