摘要： The invention relates to a method for producing maleic anhydride by heterogeneous-catalytic gas phase oxidation of a hydrocarbon flow containing n-butene with oxygen-containing gases in a tube reactor with two consecutive reaction zones. The first, educt-side reaction zone comprises at least one catalyst which is adapted to oxydehydrogenate the n-butenes to 1,3-butadiene, and the second, product-side reaction zone comprises a catalyst which is adapted to oxidize 1,3-butadiene to maleic anhydride. For doing so, a tube reactor is used which comprises at least one heat transfer circuit in the area of the first, educt-side reaction zone, and at least one further heat transfer circuit in the area of the second, product-side reaction zone.

摘要： The invention relates to a vanadium-, phosphorus- and oxygen-containing catalyst that is used for producing maleic anhydride by heterogeneous catalytic gas phase oxidation of a hydrocarbon carrying at least four carbon atoms in which the ratio of phosphorus/vanadium is 0.9 to 1.5. Said catalyst comprises particles with an average diameter of at least 2 mm and the composition has a x-ray powder diffraction pattern, obtained by irradiation with CuKα radiation (μ = 1.54 . 10-10 m), that produces in the 2υ range of 10° to 70° a signal/noise ratio of ≤ 10 for all diffraction lines that can be attributed to a vanadium- and phosphorus-containing phase. The invention further relates to a method for producing such a catalyst and to a method for producing maleic anhydride on such a catalyst.
