The invention relates to a process for preparing a shaped Cu&#x2014;Al catalyst body for the hydrogenation of organic compounds containing a carbonyl function. More particularly, the shaped catalyst body is suitable for the hydrogenation of aldehydes, ketones and of carboxylic acids or esters thereof, specifically of fatty acids or esters thereof, such as fatty acid methyl esters, to the corresponding alcohols such as butanediol. The present invention further relates to Cu&#x2014;Al catalysts obtainable by the preparation process.

Hydrogenation catalyst and process for production thereof by the use of uncalcined starting material

The invention relates to a catalyst molded body, which is produced by deforming a mixture of a metal oxide and a special graphite. The invention further relates to a method for producing the corresponding catalyst molded bodies and to the use of the catalyst molded bodies for catalytic reactions in which hydrogen acts as a reaction reactant or reaction product, in particular hydrogenation, hydrogenolysis, and dehydrogenation reactions. The catalysts are characterized by an improvement in the activity and selectivity in particular in hydrogenation, hydrogenolysis, and dehydrogenation reactions, said improvement being achieved by adding special graphites.

Catalyst molded body containing graphite

A method for producing a shaped Cu&#x2014;Zn catalyst for hydrogenating organic compounds containing a carbonyl function. The shaped catalyst is suitable for hydrogenating aldehydes, ketones and also carboxylic acids and/or their esters, fatty acids and/or their esters, such as fatty acid methyl esters, to the corresponding alcohols, dicarboxylic anhydrides, such as maleic anhydride (MAn), or esters of diacids to dialcohols, such as butanediol. The present invention further relates to Cu&#x2014;Zn catalysts obtainable by the production method.

Hydrogenation catalyst and method for producing same

Catalyst for the selective hydrogenation of multi-unsaturated organic compounds, in particular of diolefins and dienes in mixtures with other hydrocarbons; the catalyst is characterized by
