  • Hydrogenation catalyst and production process thereof
    Patent number: 5302568
    Abstract: A catalyst for hydrogenation use in which the carrier of the catalyst comprises at least one compound from oxides and hydroxides of aluminum, silicon, titanium, zirconium, magnesium and iron, zeolites or silica-alumina, and the catalyst has an atomic ratio (the atomic ratio of the entire catalyst including the carrier, in the case of the use of an aluminum atom-containing substance as the carrier) of Cu/Fe/Al/(an alkali metal and/or an alkaline earth metal)/Zn=1/0.4 to 2.5/0.5 to 5.0/0.001 to 0.4/0 to 1.0. According to the present invention, a copper-iron-aluminum catalyst having markedly high activity and selectivity can be obtained, and, when the catalyst is used, higher alcohols having high purity can be obtained easily.

  • Process for producing hydrogenation catalyst
    Patent number: 5120700
    Abstract: The hydrogenation catalyst comprises copper, iron, aluminum and optionally zine and a support selected from aluminum hydroxide, aluminum oxide and a mixture of aluminum hydroxide and aluminum oxide, having an atomic ratio of Cu/Fe/Al/Zn in the range of 1/(0.4 to 2.5)/(0.5 to 5.0)/(0 to 1.0). It is produced by dispersing a material for the support in an aqueous medium, depositing cupper and iron on the dispersant, further depositing thereon aluminum and sintering it. It is a catalyst for production of a higher alcohol from its methyl ester, effecting hydrogenation with an improved selectivity and activity.

  • Process for preparation of Guerbet alcohols
    Patent number: 4518810
    Abstract: A Guerbert alcohol is effectively and selectively obtained by heating a primary alcohol in the presence of an alkaline substance and a copper-nickel catalyst in which a weight ratio of copper to nickel is in the range of from 1:9 to 9:1.

  • Process for oxidation of monosaccharides
    Patent number: 4108891
    Abstract: Monosaccharides are oxidized by an oxygen-containing gas in the presence of a special palladium-carbon catalyst which is prepared by adsorbing palladium on active carbon at a temperature lower than 60.degree. C while the active carbon is suspended in an aqueous solution of an alkali metal hydroxide or carbonate and then reducing the palladium with formaldehyde.
