Abstract: The invention relates to a process for preparing a catalyst support, in which zirconium dioxide powder is mixed with a binder, if desired a pore former, if desired an acid, water and, if desired, further additives to give a kneadable composition and the composition is homogenized, shaped to produce shaped bodies, dried and calcined, wherein the binder is a monomeric, oligomeric or polymeric organosilicon compound. Suitable binders are monomeric, oligomeric or polymeric silanes, alkoxysilanes, aryloxysilanes, acryloxysilanes, oximinosilanes, halosilanes, aminoxysilanes, aminosilanes, amidosilanes, silazanes or silicones. The invention also provides the catalyst support which has been prepared in this way, a catalyst comprising the support and its use as dehydrogenation catalyst.

Abstract: A copper-containing catalyst of the composition of N2O contains a compound of the formula MxAl2O4, where M is Cu or a mixture of Cu and Zn and/or Mg and x is from 0.8 to 1.5. The novel catalyst is used in a process for the catalytic decomposition of pure N2O or N2O contained in gas mixtures, at elevated temperatures.

Abstract: Catalyst containing copper for decomposition of dinitrogen monoxide contains a metal oxide-alumina compound, in which the metal is copper and optionally zinc and/or magnesium and is present in an amount ranging from 0.8 to 1.5 times the stoichiometric amount for a spinel. Catalyst containing copper for decomposition of dinitrogen monoxide (N2O) contains a compound of formula (I). MxAl2O4 (I) M = copper or mixtures of copper with zinc and/or magnesium; and x = 0.8-1.5. Independent claims are also included for 2 methods of preparing the catalyst.

Abstract: The invention concerns a method of producing catalysts, containing iron and potassium and optionally other elements, suitable for the selective dehydrogenation of hydrocarbons to give the corresponding olefinically unsaturated hydrocarbons. In a first step, a finely particulate dry or aqueous mixture of an iron compound with a potassium compound and optionally also compounds of other elements is calcined in such a way that 5 to 50 mu m diameter conglomerates, made up of smaller particles, are produced. In a second step, preferably following shaping, the mixture is calcined at 300 to 1000 DEG C, the maximum calcining temperature in the second step preferably being at least 30 DEG C lower than that in the first step. The invention also concerns the use of the catalysts produced in this way, particularly in the dehydrogenation of ethylbenzene to styrene.

Abstract: A process for the catalytic-oxidising dehydrogenation of alkyl aromatics or paraffin hydrocarbons to the corresponding alkenyl aromatics or olefines by means of a redox catalyst (oxygen transmitter), in which in a first reaction stage the alkyl aromatic or paraffin hydrocarbon (educt) is dehydrogenated with a catalyst composed of a reducible metal oxide and chrominum oxide in the absence of molecular oxygen and the catalyst is reduced, and in a second stage the reduced catalyst is reoxidised with an oxidising agent.
