Abstract: In an aluminium oxide (I) catalyst for the synthesis of methyl mercaptan containing 5-25 wt.% potassium tungstate (II) as promoter with respect to active (I), (II) is deposited in 2 portions. (I) is first coated with the first portion of (II) by impregnation in excess aqueous solution, then dried at elevated temperature. Then the second portion is applied by pore volume impregnation. The catalyst precursor is then dried at elevated temperature and calcined at 200-600 degrees C.

Abstract: A formed metal solid-bed catalyst, consisting entirely of catalyst alloy (and possibly promoters) with a total pore vol. of 0.1-0.6 ml/g and with a surface shell 0.1-2.0 mm thick which is activated by complete or partial leaching of an extractable alloy component (I). Also claimed is a process for the production of thE catalyst . Preferably the catalyst metal is nickel, cobalt, copper and/or iron, and component (I) is aluminium, zinc or silicon. The catalyst may also contain up to 15 wt% chromium, iron, cobalt, tantalum, molybdenum and/or titanium as promoters.

Abstract: Production of catalytically active coatings on the surface of ceramic mouldings comprises uniformly wetting the mouldings with a coating dispersion containing a particulate Pt metal and a further coating component in a carrier fluid, vaporising the carrier fluid, and converting the coating into the catalytically active state by slowing heating in the presence of nitrogen and/or ammonia to 1000-1350 degrees C. Particulate nitrides with Al, B, Ti or Si as cations are used as the further component. The particulate components have an average particle size of
