Abstract: Oxidation catalysts which in addition to oxygen ions, with or without NH4+ ions, contain molybdenum, tungsten, phosphorus and antimony as basic components, in the atomic ratio Mo:W:P:Sb=12:0.1-3:0.1-4:0.1-3, and which are prepared in a conventional manner by combining molybdenum, phosphorus, antimony and tungsten compounds in aqueous solutions or suspensions, removing the water and calcining the residues, the combination being carried out at chloride ion concentrations of less than 0.3 mole per mole of molybdenum and in the presence of ions of monocarboxylic acids of 1 or 2 carbon atoms, dicarboxylic acids or hydroxycarboxylic acids, are particularly suitable for the gas phase oxidation of methacrolein to methacrylic acid.

Abstract: A molded catalyst for reactions carried out under heterogeneous catalysis consists of a catalytically active material shaped into hollow cylinders, or of an inert carrier which is shaped into hollow cylinders and onto which catalytically active material is applied the external diameter of the hollow cylinders being from 3 to 20 mm, the internal diameter being from 0.1 to 0.7 times the external diameter and the length being from 0.2 times to twice the external diameter. The end faces of the hollow cylinder are curved so that the radius of curvature is from 0.4 to 5 times the external diameter. The novel catalysts are particularly useful for partial oxidation in the gas phase.

Abstract: A coated catalyst comprising (a) an inert carrier having particles of not less than 100 mu m diameter and a surface area of up to 20 m2/g and (b) a coating which contains the catalytic material and adheres firmly to the outer surface and to the edge zone, near the surface, of the carrier particles, can be prepared by applying the catalytic material as a 10-70% strength suspension in water to the agitated carrier particles, which are at below 70 DEG C., if the suspension is sprayed, at a constant rate of from 0.01 to 2.0 kg of active material/hour/liter of carrier onto the carrier particles, while at the same time uniformly passing from 0.1 to 12 m3 (S.T.P.)/hour/liter of carrier of an inert gas at from 20 DEG to 300 DEG C. over the carrier particles, under conditions such that the water only evaporates incompletely but the water content of the resulting coating is less than the maximum degree of saturation of the catalytic material.
