Abstract: Following a prior reaction in the tube bundle reactor, and between extraction and re-charging, the solid layer of molybdenum oxide or and/or molybdenum oxide hydrates deposited on the insides of the reactor tubes, is brushed away. Cylindrical, especially spirally-configured tube brushes are used. The coating is brushed away immediately on its formation. The preceding process is one of heterogeneous catalysis promoting partial gas phase oxidation. Examples of prior reactions carried out, include conversion of: propylene to acrolein and/or acrylic acid, acrolein to acrylic acid, iso-butene to methacrolein and/or methacrylic acid, methacrolein to methacrylic acid, propane to acrolein and/or acrylic acid, iso-butane to methacrolein and/or methacrylic acid, propylene to acrylonitrile, propane to acrylonitrile, isobutene to methacrylonitrile, isobutane to methacrylonitrile, C 4-hydrocarbon(s) to maleic acid anhydride or methanol to formaldehyde. The after-care or servicing described, complements use of a multi-element, formed oxide catalyst, containing molybdenum oxide in its active mass. The product gas contains steam.
