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

A nanocrystalline supported or unsupported copper oxide with a residual carbon content of &#x3c;10% and a BET surface area &#x3e;95 m/g. Further, a method for the production of a supported, or unsupported nanocrystalline copper oxide is disclosed, as well as the use thereof in catalysis, in particular in the steam reforming of methanol or in the hydrogenation of esters.

Nanocrystalline copper oxide and method for the production thereof

A method for the production of a nanocrystalline bismuth-molybdenum mixed oxide, the use of the bismuth-molybdenum mixed oxide as catalyst for chemical conversions, in particular for a conversion of propylene to acrolein and/or acrylic acid or of isobutylene to methacrolein and/or methacrylic acid, as well as a catalyst that contains the bismuth-molybdenum mixed oxide.
