  • PRODUCTION AND USE OF SUPPORTED ACTIVATED BASE METAL CATALYSTS FOR ORGANIC TRANSFORMATION
    Publication number: 20090018366
    Abstract: Method for the production of supported activated metal catalysts, whereby an alloy, a metal powder, a pore builder is dispersed in a water, the dispersion is sprayed on a support which is the dried, calcined and activated. The catalysts can be used for organic transformations, i.e. for hydrogenation reactions.

  • Process For Modifying Catalysts and the Use of the Catalysts
    Publication number: 20080214387
    Abstract: Process for modifying catalysts via the deposition of carbon containing residues in the presence of one or more solvents, where the gas phase over the catalyst treatment solution during the treatment is air or an inert gas, and/or the liquid phase contains a templating agent and/or base. The modified catalyst can be used for stereo-, chemo- and regioselective transformations of organic compounds.

  • Process for the preparation of saturated organic compounds
    Publication number: 20020193618
    Abstract: Process for the preparation of completely or partly saturated organic compounds by catalytic hydrogenation of unsaturated organic compounds with hydrogen or hydrogen-containing gas mixtures in the presence of a shaped Raney catalyst as the hydrogenation catalyst, wherein the Raney catalyst is in the form of hollow bodies. Nickel, cobalt, copper, iron, platinum, palladium or ruthenium are preferably used as catalytically active constituents.
