Abstract: Disclosed is a method for long-term operation of a heterogeneously catalyzed partial gas phase oxidation of propene to obtain acrolein, in which the propene contained in the fed reaction gas mixture is partially oxidized when said gas mixture penetrates the fixed catalyst bed that is accommodated in two spatially successive temperature zones A, B, and in order to prevent the quality of the fixed catalyst bed from deteriorating during long-term operation, the temperature in at least one of the two temperature zones is raised in such a way that the difference T
B - T
A becomes greater and greater, where T
B is the temperature in temperature zone B and T
A is the temperature in temperature zone A.

Abstract: 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 A
geo (in mm
2 ), and the geometric volume V
geo (in mm
3 ) of the catalyst molded body satisfy the condition: 0.275 geo /V
geo . 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.
