摘要： A coated catalyst for the catalytic gas-phase oxidation of aromatic hydrocarbons comprises, on an inert nonporous support, a catalytically active composition comprising a defined amount of vanadium oxide, titanium dioxide, a cesium compound, a phosphorus compound, and antimony oxide, wherein the catalytically active composition is applied in two or more layers and where relative to the inner layer or inner layers the outer layer has an antimony oxide content which is from 50 to 100% lower and wherein the amount of catalytically active composition of the inner layer or layers is from 10 to 90% by weight of the amount of catalytically active composition, and can be used for preparing carboxylic acids and/or anhydrides, in particular phthalic anhydride; also specified is a production process for such catalysts.

摘要： A selective catalytic material is used in a method for selective oxidation of carbon monoxide in the presence of hydrocarbons and contains rhodium and a bismuth component either as a supported catalytic material dispersed on a refractory inorganic oxide support or as an unsupported catalytic material prepared, for example, by co-precipitation from a solution containing dissolved bismuth and rhodium salts. The bismuth and rhodium components are present in amounts that provide an atomic ratio of bismuth to rhodium in the range of from about 0.1:1 to 10:1, e.g., from about 1:1 to 2.5:1. The selective catalytic material is contacted under oxidizing conditions with a gas stream containing carbon monoxide and hydrocarbons. The selective catalytic material (24a) may be disposed on a sensor (24) disposed within a conduit (18) downstream of a conventional treatment catalyst (16) to evaluate the performance of the latter by measuring the extent of carbon monoxide oxidation catalyzed by the selective catalytic material (24a) in the treated gas.
