Abstract
Maleic anhydride is prepared in the gaseous phase by passing benzene and an oxygen containing gas under indirect heat withdrawal conditions over a solid fixed bed catalyst comprising vanadium pentoxide which exhibits a greater activity at the end portion of the oxidation zone. A catalyst of greater activity may also be placed along a short starting or priming path. The activity of the catalyst is varied by using various proportions of carrier substances, e.g. silicon dioxide, aluminium dioxide or anatase. The activity may be increased by adding ingredients such as titanium oxide, and potassium sulphate, and especially molybdenum oxide.
