Abstract: A supported catalyst (I) containing 0.1-20 wt.% rhenium and 0.05-10 wt.% platinum (with respect to the total weight of the catalyst) is prepared by: (a) treatment of the optionally pretreated support with a solution of a rhenium compound; (b) drying and heating in a reducing atmosphere at 80-600 degreesC and; (c) impregnation with a solution of a platinum compound and drying. An Independent claim is also included for a process for the production of alcohols by catalytic hydrogenation of carbonyl compounds using the catalyst (I).

Abstract: Optionally alkyl-substituted 1,4-butanediol is prepared from C 4 -dicarboxylic acids and/or of derivatives thereof by: a) introducing a gas stream of the C 4 -dicarboxylic acid or the derivative thereof in a first reactor in the gas phase to obtain a product which contains mainly optionally alkyl-substituted gamma-butyro-lactone; b) removing succinic anhydride from the product of step a); c) catalytically hydrogenating the product of step b) in a second reactor in the gas phase to obtain optionally alkyl-substituted 1,4-butanediol; d) removing the desired product from intermediates, by-products and any unconverted reactants; and e) optionally recycling unconverted intermediates into one or both hydrogenation stages. The catalysts employed in each of the hydrogenation stages comprise
