Catalysts comprising: a ground, spent (de)hydrogenation catalyst material present in an amount of 10 to 70% by weight based on the catalyst, the ground, spent catalyst material comprising iron oxide; and a fresh catalyst material present in an amount of 30 to 90% by weight based on the catalyst, the fresh catalyst material comprising iron oxide, wherein at least a portion of the iron oxide in the fresh catalyst material comprises a phase selected from the group consisting of hematite, potassium ferrite, and mixtures thereof are described along with processes for preparing and using the same.

Catalysts for dehydrogenation and/or hydrogenation of hydrocarbons, processes for preparing the same, and uses therefor

The invention relates to a method for hydrogenation of an organic compound comprising at least one carbonyl group, whereby the organic compound is brought into contact with a moulded body in the presence of hydrogen. Said body may be produced by a method in which (i) an oxidic material is prepared, comprising copper oxide, aluminum oxide, and at least one oxide of lanthanum, tungsten, molybdenum, titanium, or zirconium, followed by (ii) addition of powdered metallic copper, copper platelets, powdered cement, graphite, mixtures or a mixture thereof with graphite to the oxidic material and (iii) moulding the mixture from (ii) to give a moulded body, characterised in that the moulded body is in the form of catalyst tablets or catalyst extrudates with a diameter d and/or height h&#x3c;2.5 mm, catalyst beads with a diameter d&#x3c;2.5 mm or catalyst honeycomb with a cell diameter r&#x3c;2.5 mm.
