Catalyst resins are insoluble, polymeric beads which are used in different industries for various processes. Thermax offers specialty Tulsion® range of polymeric catalysts that are available in hydrogen and hydroxyl form. The hydrogen form catalyst is used for reactions that are normally catalysed by mineral acids, whereas the catalyst in hydroxyl form is used for base catalysed reactions. 

Tulsion® resins are widely used as catalysts in heterogeneous catalysis for providing excellent kinetic performance. Tulsion® catalyst can be used in agitated reactors as well as in continuous fixed bed reactors.

Advantages of Tulsion® catalysts over homogeneous acid catalysts
  • Ease of separation from reaction mixtures hence suitable for continuous reactions
  • No necessity to neutralise or concentrate the catalyst
  • Can be re-used over number of process cycles
  • Elimination of waste disposal problems
  • Higher selectivity to the desired product and fewer by products
  • Clean and safe processes with desired rate of reaction and higher yields
