Abstract:
1. A process for the production of a catalyst composition comprising a catalytically active oxidic composition of cesium and tungsten having a molar ratio of cesium to tungsten of less than or equal to 1.6:1 wherein said catalytically active oxidic composition is supported by an oxidic inorganic support body comprising the steps of: a) impregnating a support body or a support material with an aqueous solution of soluble cesium and tungsten at a molar ratio of cesium to tungsten of less than or equal to 1.6:1, to form an impregnated support, b) pre-drying the impregnated support at room temperature, c) optionally further drying the pre-dried impregnated support at 100 to 200° C. to remove any residual moisture, and d) calcining the pre-dried or dried impregnated support for a period of 2 to 10 hours at a temperature ranging from 300 to 600° C.
