Overview

Catalysis Products

While ordinary commercial styrene-based sulfonic acid resins may often be used for chemical reactions catalyzed by the H+ or M+ ions, faster process times, better yields, and higher product purity may be obtained by using a properly designed and purified catalyst. Purolite catalyst resins are supplied either completely water-swollen, or dried to specification.

Our catalyst products are used in many applications in the chemical and petrochemical industries.

 

  • Acid catalysis for reduced by-product formation 
  • Biodiesel feedstock pretreatment and purification 
  • Bisphenol-A synthesis
  • MTBE, ETBE and TAME production
  • Etherification, aromatic alkylation, phenol purification and olefin hydration
