Definitions

  • the promoter components are added before, during or after the reaction of the vanadium pentoxide in the presence of the reducing organic solvent or with the phosphorus compound. Alternatively, it is possible to add it after completion of the precipitation (preferably at reduced temperature) and, if appropriate, a renewed heating.
  • the content of promoters is generally in total in the finished catalyst generally not more than about 5 wt .-%, each calculated as oxide.
  • the proportion of crystalline vanadyl pyrophosphate can be adjusted.
  • the catalysts of the invention can be used for the gas phase oxidation of hydrocarbons, in particular for the production of maleic anhydride by gas phase oxidation of hydrocarbons having at least four carbon atoms.
  • the process according to the invention can be carried out at a pressure below normal pressure (for example up to 0.05 MPa abs) or above normal pressure (for example up to 10 MPa abs). Preference is given to a pressure of 0.1 to 1.0 MPa abs, more preferably 0.15 to 0.7 MPa abs.
  • Catalyst precursor D-1 was prepared as in Example A-1, with the difference that instead of VPO precursor A, the significantly coarser VPO precursor D was used.
  • the catalyst prepared in this way was examined for its abrasion resistance (compare abrasion test) and its catalytic performance (see catalytic tests). The corresponding values are summarized in Table 5.
  • the preparation of the catalyst 3 was carried out as described in Example 1, with the difference that instead of the catalyst precursor A-1, the catalyst precursor A-2 was used.
  • the catalyst prepared in this way was examined for its abrasion resistance (compare abrasion test) and its catalytic performance (see catalytic tests). The corresponding values are summarized in Table 5. Due to the coarser SiO 2 species used, the catalyst shows a still acceptable, but not optimal abrasion resistance.
  • the preparation of the catalyst 5 was carried out as described in Example 1, with the difference that instead of the catalyst precursor A-1, the catalyst precursor C-1 was used.
  • the catalyst prepared in this way was examined for its abrasion resistance (compare abrasion test) and its catalytic performance (see catalytic tests). The corresponding values are summarized in Table 5. With good abrasion resistance, the yield of MSA achievable with this catalyst is clearly below the target value due to the encapsulation with SiC "2.
