Abstract (en)
[origin: WO2010072721A2] The catalytically active mass of a catalyst molded body comprises a multi-element oxide containing vanadium and phosphorus. The specific pore volume PV (in ml/g) of the catalyst molded body, the bulk density p of the catalyst molded body (in kg/l), the geometric surface area Ageo (in mm2), and the geometric volume Vgeo (in mm3) of the catalyst molded body satisfy the condition: 0.275 geo/Vgeo. In a method for producing maleic acid anhydride by heterogeneously catalytic gas phase oxidation of a hydrocarbon, the catalyst molded body allows a lower pressure loss and a high yield.
