Abstract: Catalysts suitable for hydrogenating organic compounds, essentially containi ng 65 to 80 % nickel calculated as nickel oxide, 10 to 25 % silicon calculated as silicon dioxide, 2 to 10 % zirconium calculate d as zirconium oxide, 0 to 10 % aluminium calculated as aluminium oxide, with the proviso that the sum of the silicon dioxide and al uminium oxide contents is at least 15 %, with the percen tages by weight in relation to the total mass of the catalyst, obtainable by the a ddition of an acid aqueous solution of nickel, ziconium and, if desired, aluminium salts to a basic aqueous solution or suspension of silico n compounds and, if desired, aluminium compounds, the pH of the mixture thus obtained being reduced to at least 6.5 and subsequently adjusted to 7 to 8 by the addition of a further basic so lution, isolation of the solid thus precipitated, drying, shaping and calcinating, i n addition a process for producing the catalysts and the ir use in the production of medicinal white oil, highly pure medicinal paraffins and low-b oiling-point non-aromatic hydrocarbon mixtures.

Abstract: A catalyst packing which can be produced by vapor deposition and/or sputtering of at least one substance active as catalyst and/or promotor onto woven or knitted fabrics or sheets as support material is used in a process for catalytic distillation in which a heterogeneously catalyzed reaction is combined with a simultaneous distillation or rectification over the catalyst packing.

Abstract: The invention relates to a shell catalyst with a core and at least one shell surrounding the core, said core being composed of an inert carrier material, and the at least one shell being composed of a porous carrier substance. The shell is physically adhered to the core and the at least one shell contains a catalytically active metal selected from the group of metals of the 10th and 11th group of the periodic table of elements in a finely divided form, or a precursor of the catalytically active metal in a uniformly divided form. The inventive shell catalyst is suitable for reducing unsaturated hydrocarbons a nd allows for better selectivities in comparison with shell catalysts known so far. The invention further relates to a method for producing the inventive shell catalyst.

Abstract: The use of a catalyst package which can be produced by the vapour deposition and/or sputtering of at least one substance active as a catalyst and/or promotor on fabrics, knitted materials or foils as substrates in a catalytic distillation process in which a heterogeneous-catalytic reaction is combined with simultaneous distillation or rectification on the catalyst package.

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.
