Abstract: In a coated catalyst having a core and at least one shell surrounding the core, the core is made up of an inert support material, the shell or shells is/are made up of a porous support substance, with the shell being attached physically to the core, and a catalytically active metal selected from the group consisting of the metals of the 10th and 11th groups of the Periodic Table of the Elements is present in finely divided form or a precursor of the catalytically active metal is present in uniformly distributed form in the shell or shells. The coated catalyst of the present invention is suitable for the reduction of unsaturated hydrocarbons. Here, better selectivities than in the case of previously known coated catalysts can be achieved. A process for producing the coated catalyst is also described.

Abstract: Selective hydrogenation of alpha , beta -ethylenically unsaturated aldehydes (II) to corresponding unsaturated alcohols (I) comprises performing reaction in a reactor containing a liquid phase, suspended catalyst and optionally a gas phase, The liquid phase and gas phase (if present) are supplied to the reactor through a device (A) with openings or channels having a hydraulic diameter of 0.5-2 mm. Selective hydrogenation of unsaturated aldehydes of formula R R C=CR -CHO (II) to corresponding alcohols of formula R R C=CR -CH2OH (I) comprises performing the reaction in a reactor containing a liquid phase, suspended catalyst and optionally a gas phase. The liquid phase and optionally the gas phase are supplied to the reactor through a device (A) with openings or channels having a hydraulic diameter of 0.5-2 mm. R , R = H, optionally substituted mono- or polyunsaturated 1-20C alkyl (sic; some of the groups exemplified in the disclosure are saturated), optionally substituted aryl or optionally substituted heterocyclyl; R = H or 1-4C alkyl.

Abstract: The present invention relates to a process for isomerizing reactant allyl alcohols to product allyl alcohols in the presence of a catalyst, wherein the reactant allyl alcohol is rearranged to product allyl alcohol in semicontinuous or continuous mode in a catalyst-containing suitable reactor. In particular, the process according to the invention is used to prepare linalool from Geraniol and/or nerol.

Abstract: For a process for the catalytic conversion of fuel for removing oxides of nitrogen from exhaust gases of internal combustion engines, in which fuel and a part- stream of the exhaust gas or of the intake air are converted in a converter, the fuel and the part-stream of the exhaust gas or of the intake air are fed separately from one another into the converter and the fuel is vaporized in the converter. A converter for the catalytic conversion of fuel, comprising a vaporization space and a conversion space connected thereto is furthermore described, the vaporization space having separate feeds for exhaust gas or intake air and fuel, the conversion space having a catalyst for the catalytic conversion of fuel and the vaporization space and the conversion space being connected to one another so that heat transport from the conversion space into the vaporization space is possible.

Abstract: In a process for preparing a multiplephase multimetal oxide composition comprising Mo, V, Cu and, if desired, further elements, at least one phase is preformed separately and dispersed in a plastically deformable precursor composition of a further phase. The mixture is dried and calcined. The multimetal oxide composition is suitable as active composition of catalysts for the catalytically oxidation of organic compounds in the gas phase, in particular for the oxidation of acrolein to acrylic acid.
