    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.

    Abstract: Catalyst for oxidn. of SO2 to SO3 consists of a SiO2 support activated with V and alkali metal cpds. The support: has a pore vol. fraction of 10-30% pores with dia. up to 15nm, 25-60% pores with dia. 15-200 nm and 10-60% pores with a dia. of over 200nm. The catalyst is produced by mixing SiO2 of the specified pore dia. with enough liquid (water and/or H2SO4) to give a mouldable mixt., moulding, drying and calcining the moulding (at 450-650 deg.C), impregnating the calcined material with activators and drying. USE/ADVANTAGE - The catalyst has very good mechanical properties (hardness and attrition in both the fresh and aged state), high activity over a wide temp. range (ca. 380-420 deg.C) and very low pressure drop. The high activity at relatively low temp. makes it possible to reduce operating costs by using a lower temp. than usual and also reduces SO2 emissions at low temp.

    Abstract: Alkines, dienes, and/or singly unsaturated hydrocarbons; compounds containing sulphur, arsenic and/or antimony; oxygen, hydrogen and/or carbon monoxide are removed from material flows in a total of at most three process steps. In a first process step, after hydrogen has been added to the feed material flow at a hydrogenation catalyst which is largely resistant to compounds containing sulphur, arsenic and/or antimony, alkines, dienes and/or singly unsaturated hydrocarbons are removed by hydrogenation, oxygen which may optionally be present also being at least partially removed by hydrogenation. In a second process step, compounds containing sulphur, arsenic and/or antimony and/or residual oxygen from the first process step are removed by absorption on a contact mass, and/or residual oxygen, carbon monoxide and/or residual hydrogen are at least partially converted catalytically into water and carbon dioxide. Optionally, in a third process step, residual carbon monoxide and/or residual hydrogen from the preceding process steps is/are converted on a contact mass into carbon dioxide and/or water.

    Abstract: A process for preparing 1,2-dichloroethane by reacting about 2 mols of ethylene, about 4 mols of hydrogen chloride and about 1 mol of oxygen in the presence of a fixed bed of supported catalyst based on copper(II) chloride in only one reaction zone at a pressure of from 2 to 10 bar and at from 220 to 280° C., separating off 1,2-dichloroethane and water from the reaction mixture emerging from the reaction zone and passing most of the exhaust gas back into the reaction zone, where, prior to entry into the reaction zone, the exhaust gas is mixed with ethylene, hydrogen chloride and oxygen, and the oxygen content of the mixture does not exceed 7% by volume, and where the ethylene content of the gas mixture entering into the reaction zone is regulated so that the exhaust gas comprises less than 20% by volume of ethylene, where the supported catalyst used is obtained by tableting a mixture of pseudoboehmite and gamma-Al2O3 in a weight ratio from 4:1 to 1:4, if desired with addition of tableting auxiliaries, loading this support with the active components by saturating with a CuCl2/KCl solution so that the copper content is from 1 to 15% by weight and the potassium content is from 0.1 to 8% by weight, based in each case on the total weight of the catalyst, and then drying the catalyst at from 60 to 400° C.
