Abstract: Disclosed is a method for producing a catalyst containing vanadium, phosphorus, and oxygen, which is used for oxidizing the gas phase of a hydrocarbon having at least four carbon atoms to maleic anhydride. According to the inventive method, a corresponding catalyst precursor which contains vanadium, phosphorus, and oxygen and is provided with particles having an average diameter of at least 2 mm is converted into a catalytically active form by means of calcination, and a flow of the catalyst precursor is transported on a conveyor belt across at least one calcination area over a distance ln at an essentially steady speed in order to be calcinated. The variation over time of the gas temperature in relation to the set point value amounts to ≤ 5 °C at each position in the area of the flow of the catalyst precursor, which lies within the second half ln/2 of the calcination area, while the local difference in the gas temperature between any positions in the area of the flow of the catalyst precursor, which is located within the second half ln/2 of the calcination area, amounts to ≤ 5 °C.

Abstract: The invention relates to a method for producing a catalyst-precursor containing vanadium, phosphorous and oxygen for the production of maleic acid anhydride by means of heterogeneous catalytic gas phase oxidation of a hydrocarbon having at least four hydrocarbon atoms, wherein (a) vanadium pentoxide is reacted with 102 - 110 % phosphorous acid in a temperature range of between 80 - 160 °C in the presence of a primary or secondary, non-cyclic or cyclic, non-branched or branched, saturated alcohol having 3 - 6 carbon atoms; (b) the formed deposit is isolated; (c) a content of organic carbon of = 1.1 wt. % is adjusted in the insulated deposit by tempering in a temperature range of between 250 - 350 °C, whereby the tempered product produces a powder-x ray diffraction diagram after the addition of 3.0 wt. % graphite, said diagram having a peak height ratio of the peak in the 2?-range of = 0,1 of a possibly existing pyrophosphate phase at 28.5° to the peak at 26.6° emerging from the graphite and, d) the tempered product obtained from step c) is formed to obtain particles having an average diameter of at least 2mm. The invention also relates to a catalyst-precursor obtained according to said method for producing a catalyst from the catalyst-precursor, a catalyst which can be obtained according to said method, in addition to a method for producing maleic acid anhydride on said catalyst.
