    摘要: A copper oxide based catalyst for dehydrogenation of cyclohexanol which is a copper oxide-zinc oxide based catalyst or a copper oxide-silicon oxide based catalyst further comprising one of palladium, platinum and ruthenium in a very small amount; and a method for preparing the copper oxide based catalyst which comprises combining the co-precipitation method or the kneading method and the spray method. The copper oxide based catalyst for dehydrogenation of cyclohexanol exhibits high activity and high selectivity, and thus may be used for producing cyclohexanone at a reduced reaction temperature and/or with an enhanced yield, as compared to a conventional catalyst.

    摘要: A palladium-base catalyst can selectively hydrogenate highly unsaturated hydrocarbon compounds contained in small amounts in an olefin compound prepared by steam cracking or the like of naphtha without causing hydrogenation of the olefin as a side reaction and the precipitation of a carbonaceous material. The catalyst comprises palladium and alumina, and the exposed face of each palladium crystallite is mainly accounted for by (100) and (110) faces. Further, in the desorption of absorbed hydrogen by heating, desorption peaks are observed in the temperature ranges of 40 to 90.degree. C. and of 120 to 170.degree. C. and the ratio of hydrogen desorption amount of the former to the latter is (4:6) to (3:7).
