Abstract: A process for activating fluid bed catalysts useful for producing maleic anhydride from 4 carbon atom hydrocarbons is provided including contacting the fluidized catalyst containing the mixed oxides of vanadium and phosphorus with oxygen and a reducing gas at least partially combustible with oxygen at elevated temperatures sufficient to cause such combustion, wherein the molar ratio of reducing gas to oxygen is below the stoichiometric ratio required for complete combustion of the reducing gas. Also provided are catalysts activated by the process of the invention, as well as a process for producing maleic anhydride utilizing the catalysts thus activated.

Abstract: The present invention provides a process for the preparation of oxidation catalysts containing mixed oxides of vanadium and phosphorus, which catalysts are particularly effective in the oxidation of n-butane, n-butanes, 1.3-butadiene of a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapor phase to produce high yields of maleic anhydride with good selectivity. A vanadium compound is introduced into a liquid medium, a mixed phosphorus component comprising orthophosphoric acid and pyrophosphoric acid is added to the liquid medium, reduction of at least a portion of the vanadium to a +4 valence state is effected either prior to or subsequent to the addition of the mixed phosphorus component, and the resulting vanadium-phosphorus oxide catalyst precursor is recovered, dried and calcined.

Abstract: Vanadium-free catalysts consisting essentially of oxides of titanium and phosphorus have been found to be especially effective in the oxidation of n-butane, n-butenes and 1,3-butadiene with molecular oxygen in the vapor phase to yield maleic anhydride. The reaction with n-butane gives an especially pure product in good yield and selectivity.

Abstract: Catalysts containing the oxides of vanadium, phosphorus and uranium have been found to be especially effective in the oxidation of n-butane, n-butenes and butadiene with molecular oxygen in the vapor phase to yield maleic anhydride. The reaction with n-butane gives an especially pure product in high yield.

Abstract: Coated catalysts having an inert support material with an outer surface and a coating of active catalyst containing tungsten, vanadium and molybdenum plus optionally one or more of Fe, Mn, Cu, Sn, Sb, Cr, Ce, U, Co, Ni, Zn, Mg or mixture thereof have been found to be especially effective catalysts for the production of unsaturated acids from the corresponding unsaturated aldehydes, for example, acrolein is oxidized to acrylic acid using these catalysts. The catalysts give a very low exotherm, very high single pass yields of the desired acid and reduce the undesirable by-products.
