    摘要: A process is disclosed for the production of high purity mullites. The process involves reacting a mixture of aluminum alkoxide and silicon alkoxide with an atomic ratio (weight) of Al/Si in the range of 2-7 in an aromatic hydrocarbon solvent at a temperature of 200.degree.-350.degree. C. and calcining the resulting reaction product at a temperature above 900.degree. C. The mullite product obtained finds wide application as a high temperature service structural material such as for automotive engines and turbines as well as a support for combustion catalyst.

    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: 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%.
