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: The application relates to the preparation of a sulphur-free iron-oxide- and chromium-oxide-containing high temperature conversion catalyst, an iron oxide being used which is prepared from iron carbonyl and which has a mean grain size below 10 mu m and a specific surface area of more than 10 m /g. The chromium oxide component is applied to the iron oxide by precipitation. The chromium component used is CrO3 and is precipitated as insoluble chromium(III) compounds by reducing agents.

Abstract: The application relates to a process for the preparation of sulphur-free iron-oxide- and chromium-oxide-containing catalysts having BET surface areas of 20 to 100 m /g and in which more than 80% of the pore volume is in the pore radius range of 30 to 100 nm, an iron(III) oxide prepared from iron carbonyl having a mean grain size below 10 mu m and a BET surface area of greater than 50 m /g and chromium(III) oxide having a mean grain size below 40 mu m and a BET surface area of more than 30 m /g being mechanically mixed as powder or suspension and then tableted.

Abstract: A honeycomb catalyst consisting of from 30 to 95% by weight, calculated as Fe2O3, of an iron compound and from 0.1 to 60% by weight, calculated as Al2O3, CeO2 or Cr2O3, of an aluminum, cerium and/or chromium compound and/or from 1 to 50% by weight of an alkali metal compound, in particular potassium, calculated as K2O, and/or from 0.2 to 20% by weight, calculated as MeO3, of an element of sub-group 6, preferably MoO3 and WO3, and/or from 0.1 to 20% by weight, calculated as V2O5, of a compound of vanadium and/or from 0.1 to 20% by weight, calculated as P2O5, of a compound of phosphorus, a process for the preparation of the honeycomb catalyst, and the use of the catalyst for organic reactions.
