The present invention relates to an improved chromium-free Cu-Al catalyst for the hydrogenation of carbonyl groups in organic compounds, characterized in that the catalyst contains a proportion of zirconium in an amount of% to% by weight. The present invention additionally also relates to the preparation of the catalyst and to the use thereof in the hydrogenation of carbonyl groups in organic compounds.

Chromium-free water- and acid-stable catalyst for hydrogenation reactions

The present invention relates to an improved catalyst on the basis of a shaped catalyst body for hydrogenating carbonyl groups in organic compounds under the effect of acids and water, characterized in that the shaped catalyst body contains copper in an amount of 17.5 to 34.5 wt. %, relative to the shaped catalyst body and the copper is present in the shaped catalyst body to at least 70% in the form of a copper spinel CuAlO. The invention also relates to the production of the catalyst an to the use of same in the hydrogenation of carbonyl groups in organic compounds in the presence of acids and/or water.

The present invention relates to a novel process for preparing a phosphorus-containing catalyst, in which a steam treatment of the catalyst is effected, and to the catalyst obtainable thereby, and to the use thereof in a process for preparing olefins from oxygenates. The steam treatment of the catalyst typically precedes modification of the catalyst with a phosphorus compound.
