Abstract: Catalyst, in particular for the dehydrogenation of hydrocarbons to give olefinically unsaturated hydrocarbons, which essentially comprises in the sintered, ready-to-use state a) 60 to 95% by weight of at least one iron compound, calculated as Fe2O3; b) 1 to 25% by weight of at least one potassium compound, calculated as K2O; c) 0.1 to 5% by weight of at least one compound of chromium or of aluminium, calculated as Cr2O3 or Al2O3; d) 0.1 to 5% by weight of at least one compound of molybdenum or tungsten, calculated as MoO3 or WO3; e) 0.1 to 2.5% by weight of a vanadium compound, calculated as V2O5; f) 0.1 to 5% by weight of a lithium compound, calculated as Li2O; and conventional contaminants and production-related residues, as is obtained when a mixture of either Fe2O3 or FeOOH or a mixture of Fe2O3 and FeOOH and the subsidiary constituents in the form of their compounds is moulded, dried if appropriate at below 160@C and calcined at 200 to 1000@C, the atomic ratio of vanadium to molybdenum or tungsten being 1 to 2.5 and when Fe2O3 is used as starting material in production, the content of vanadium being selected in such a way that in the finished catalyst it is 0.5 to 2% by weight, when FeOOH is used as starting material it is 0.5 to 2.5% by weight and when a mixture of Fe2O3 and FeOOH is used it is no more than 1.5% by weight, in such a manner that when ...

Abstract: Disclosed is a silver-containing carrier catalyst for the decomposition of nitrous oxide present as the pure gas or in gas mixtures. The carrier catalyst includes an aluminium oxide carrier with a BET surface area of 26 to 350 m /g. Also disclosed is a method in which the carrier catalyst proposed is used for the selective catalytic decomposition of nitrous oxide present as the pure gas or in gas mixtures at elevated temperatures.

Abstract: The invention concerns a method of producing olefinically unsaturated compounds such as styrene by the oxidative dehydrogenation of suitable hydrocarbons, using a pre-oxidised oxygen carrier which acts as a catalyst, in the absence of molecular oxygen, and the re-oxidation of the oxygen carrier in at least two reactors in which dehydrogenation and regeneration take place alternately and which are connected thermally via heat exchangers and a common heat-carrier circulation system.

Abstract: Described is a method for the catalytic oxidative dehydrogenation of alkyl aromatics or paraffin hydrocarbons to the corresponding alkenyl aromatics or olefins, respectively, by means of a redox catalyst (oxygen carrier). In a first step, the alkyl aromatic or paraffin (educt) is dehydrogenated, in the absence of molecular oxygen, by a solid catalyst consisting of reducible magnesium vanadate(V) which may or may not be on a carrier, the catalyst being reduced in the process, and in a second step the reduced catalyst is re-oxidized with an oxidizing agent, the two steps being carried out in alternation at separate times or in separate locations.

Abstract: A dehydrogenation catalyst contains (a) from 40 to 90% by weight of iron, calculated as Fe2O3, (b) from 5 to 40% by weight of potassium, calculated as K2O, (c) from 0.01 to 10% by weight of vanadium, calculated as V2O5, (d) from 0.01 to 20% by weight of tungsten, calculated as WO3, (e) from 0.01 to 30% by weight of a rare earth metal, calculated as the oxide of the highest oxidation stage in each case, (f) from 0.01 to 15% by weight of aluminum, calculated as Al2O3, and (g) up to 10% by weight of cobalt, calculated as CoO. The catalyst is particularly suitable for the dehydrogenation of ethylbenzene to styrene in the presence of steam.
