Toll manufacturing

In toll manufacturing projects the composition of the catalyst and its manufacturing process as well as the process in which the catalyst is applied are well defined and elaborated. Evonik transfers catalyst production to its site and produces the catalyst to your specification.

For fixed bed catalysts we have a broad range of capabilities which help to produce the catalysts to your specification:

  • Impregnation/precipitation
  • Drying
  • Extrusion
  • Tableting/pelleting
  • Spray-drying
  • Powder mixing
  • Hot-spray impregnation
  • Reduction with hydrogen (up to 50 vol.-% H2 in N2)
  • Passivation of pyrophoric catalysts
  • Calcination in air, nitrogen and steam (stationary and continuous)
  • Regeneration (e.g. washing with water and acids, drying, removal of dust and volatile organic compounds VOC, and coke combustion)
