  • Patent number: 4673693
    Abstract: A process for preparing oxygen-containing organic compounds from synthesis gas which comprises contacting the synthesis gas with a solid catalyst prepared by the steps of: mixing (A) a copper compound, (B) a nickel compound and (C) a zinc compound; calcining the mixture; mixing the calcined product with (D) a potassium compound; and then reducing the resulting mixture.The selectivity of alcohols such as ethanol and propanol is high in the process of the present invention. The catalyst of the present invention can be used effectively over long periods of time, since the dissipation of the nickel component in the catalyst during the reaction is decreased.
    Type: Grant

  • Patent number: 4564643
    Abstract: A process for producing a mixed alcohol by contacting a synthesis gas with a catalyst, wherein the catalyst is a solid substance prepared by:calcining a mixture of (A) a zinc compound, (B) a compound of at least one metal selected from iron, cobalt, and nickel, and (C) a compound of at least one metal selected from the metals belonging to Groups II-VII of the Periodic Table;impregnating the above-calcined product with (D) an alkali metal compound and/or an alkaline earth metal compound;calcining the resulting mixture; andreducing the thus-calcined product.The selectivity of the mixed alcohol is high in the process of the present invention. This is one of the advantages of the present invention. Furthermore, the proportion of alcohols other than methanol in the mixed alcohol is relatively high, and thus the mixed alcohol is suitable for use as an alcohol component to be compounded to gasoline.
