Abstract: A supported catalyst composition for the oxychlorination of ethylene comprises 3-12 wt.% copper as copper salt and 0.001-0.1 (0.005-0.05) wt.% of ruthenium, rhodium, palladium, osmium, iridium and/or platinum and/or 0.0001-0.1 (0.001-0.05) wt.% gold as the corresponding metal salt of tetrachloroauric acid. A catalyst composition (I) for the oxychlorination of ethylene comprises a mixture of metal salts on a support and consists of (wt. % with respect to total weight of the catalyst including support): (A) copper as copper salt (3-12); (B) an alkaline earth metal as a salt (0-3); (C) an alkali metal as a salt (0-3); and (D) ruthenium, rhodium, palladium, osmium, iridium and/or platinum (0.005-0.05) and/or gold as the corresponding metal salt of tetrachloroauric acid (0.001-0.05). An Independent claim is also included for a process for the production of 1,2-dichloroethane by oxychlorination of ethylene using the catalyst composition (I).

Abstract: Catalyst contains 0.05-1.0 wt.% of a group 10 metal (compound) and 0.05-1.0 wt.% of a group 11 metal (compound). The weight ratio of the group 11 metal to the group 10 metal is 0.95-1.05. The catalyst is supported on a silicon dioxide support having a BET surface area of 2-400 m /g. At least 20% of the total pore volume of the catalyst is present in pores having a diameter above 100 nanometers An Independent claim is also included for a process for removing alkynes, dienes and simple unsaturated hydrocarbons and/or oxygen from material streams by reacting the material stream with hydrogen over a catalyst containing 0.05-1.0 wt.% of a group 10 metal (compound) and 0.05-1.0 wt.% of a group 11 metal (compound).

Abstract: The invention relates to a method for producing a supported catalyst used for the production of 1,2-dichloroethane by tabletting a mixture of pseudo-boehmite and gamma alumina at a weight ratio of between 4:1 to 1:4, possibly with the addition of tabletting aids. Said support is then charged with the active components by impregnation with a CuCl2/KCl solution such that the copper content is between 1 and 15 weight % and the potassium content is between 0.1 and 8 weight %, in each case in relation to the total mass of the catalyst. The catalyst is then dried at between 60 and 400 DEG C. In addition to the elements copper and potassium the catalyst can be charged with elements from the group comprising Li, Na, Cs, Mg, Ca and the rare-earth metals.

Abstract: The invention relates to a catalyst comprising alpha -aluminium oxide as the support material and copper as the active constituent, the BET surface (as defined in DIN 66131) of the aluminium oxide being not lower than 30 m /g. It also relates to a process for preparing said catalyst according to the invention, and the use thereof in dehydrogenation of cyclohexanol to form cyclohexanone, and also to the use of alpha -aluminium oxide, the BET surface (as defined in DIN 66131) of said aluminium oxide being not lower than 30 m /g, to prepare a catalyst.
