    摘要： There is disclosed a catalyst support for selective gas phase reactions in a tubular fixed bed reactor comprising a metallic monolith having channels the walls of which are adapted to receive a catalytically active phase or an intermediate layer acting as a carrier for a catalytically active phase. The monoliths are coated with catalytically active material and loaded lengthwise into tubular reactors, the channels being parallel to the length of the reactors. The catalysts are particularly useful in the chlorination/oxychlorination of alkenes and alkanes, and the oxidation of alkenes. Compared with the use of conventional catalysts in pellet form or in the form of ceramic monoliths the catalysts of the invention offer greater yields and selectivity, the avoidance of hot spots, greater catalyst life and flexibility in use.

    摘要： This invention provides a catalyst composition suitable for the gas phase oxidation, ammoxidation and oxidative dehydrogenation of olefins to unsaturated aldehydes, unsaturated nitriles and dienes respectively. The catalyst composition comprises, as active catalyst component, a solid solution of Fe, Sb and Ti oxides which has a rutile type crystal structure which is present in the composition in an amount of at least 80 wt. %, and which is represented by the empirical formula Fe.sub.x Sb.sub.y Ti.sub.z O.sub.w, wherein, for x=1, y is in the range of 0.5 to 10, z is in the range of 0.16 to 209 and w represents the number of oxygen atoms corresponding to the oxides of the above elements. The catalyst component is prepared by co-precipitating metal oxides from solutions of corresponding metal salts followed by calcination at 600.degree.-1000.degree. C. of the washed and dried precipitate.
