A method is for producing monolithic substrate catalysts and for their use in the gas phase oxidation of hydrocarbons. The catalysts are obtained by coating the catalyst substrate with a suspension that includes a catalytically active compound and one or more surfactants of the general formula R Y X. R represents the hydrophobic part of the surfactant, with n being 1, 2 or 3. Y represents the hydrophobic part of the surfactant, with m being 0, 1, 2, or 3 and X represents the hydrophilic head group of the surfactant.

Methods of producing monolithic oxidation catalysts and their use in gas phase oxidation of carbohydrates

The invention relates to a shell catalyst for producing acetic acid by gas-phase oxidation of unsaturated C,-hydrocarbons, comprising an inert non-porous carrier and a catalytically active mixed oxide material applied on the outer surface of the carrier, wherein said material contains (a) one or several oxides from the group titanium dioxide, zircon dioxide, stannic dioxide, aluminum oxide, and b) 0.1 to 1.5 wt. % vanadium pentoxide in relation to the weight of the constituent (a) and per m,/g of the specific surface of the constituent (a).
