    摘要: The catalyst exhibiting hydrogen spillover effect relates to the composition of a catalyst exhibiting hydrogen spillover effect and to a process for preparing the catalyst. The catalyst has a reduced transition base metal of Group VIB or Group VIIIB, such as cobalt, nickel, molybdenum or tungsten, supported on a high porous carrier, such as saponite, the base metal being ion-exchanged with at least one precious metal of Group VIIIB. The process includes the steps of loading the base metal onto the support, reducing the base metal, preferably with H2 at 600° C., and thereafter ion-exchanging the precious metal with the base metal. Preferred examples of the catalyst include a saponite support loaded with about 10-20 wt % cobalt and about 0.1-1 wt % precious metal. The catalyst is optimized for reactions that occur in commercial processes at about 360-400° C., such as in hydrocracking.

    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.
