The invention relates to a copper manganese-based catalyst on the basis of a tablet-form shaped catalyst body, comprising calcium aluminate as a binder, for hydrating carbonyl groups in organic compounds, characterised in that said shaped catalyst body comprises calcium aluminate in an amount of 0.5 to 20 wt. %. The invention also relates to the production of the catalyst and to the use of same in the hydration of carbonyl groups in organic compound.

Tablet-form copper manganese-based catalyst with increased stability against the action of acid

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. 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

The present invention relates to a particle filter comprising a porous carrier body, an SCR active component and an oxidation catalyst, wherein the SCR active component is present as coating on the exhaust-gas entry surface and the inner surface of the porous carrier body and the oxidation catalyst as coating on the exhaust-gas exit surface of the porous carrier body. According to the invention the oxidation catalyst changes its function depending on operating conditions. In normal operation it serves as NHslip catalyst for oxidizing excess NHand during filter regeneration it operates according to the 3-way principle for converting NOand CO. The invention also relates to a method for producing the particle filter, the use of the particle filter for treating exhaust gases from the combustion of fossil, synthetic or biofuels as well as an exhaust-gas cleaning system which contains the particle filter according to the invention.
