    摘要: A process for manufacturing catalysts containing, as oxides, iron, chromium, potassium, as well as a rare earth metal in a proportion, calculated in oxide weight, of 1-15% with respect to the final catalyst, comprises:a first step, wherein a product is prepared by a reaction between compounds of rare earth metal(s) and of another metal selected from Fe, Cr, Co, Al or V, and a calcination; anda second step wherein a mixture is formed between the product resulting from the first step, the other necessary reactants and water; the resulting paste is dried after optional shaping and calcined. A clayish material can be used in the step.The catalysts obtained present an improved efficiency in dehydrogenation reactions, particularly of ethylbenzene to styrene.
