The invention relates to Cu&#x2014;Al&#x2014;Mn shaped catalyst bodies in extruded form, and to a process for their preparation. The shaped catalyst body is suitable for the hydrogenation of organic compounds containing a carbonyl function, in particular for the hydrogenation of aldehydes, ketones and carboxylic acids and/or their esters. In particular, the shaped catalyst body is suitable for the hydrogenation of fatty acids or their esters, such as fatty acid methyl esters, to form the corresponding alcohols and dicarboxylic acid anhydrides, such as maleic anhydride, or esters of di-acids and di-alcohols, such as butane diol.

Extruded Cu&#x2014;Al&#x2014;Mn hydrogenation catalyst

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.
