Catalyst Products

Purolite manufacturers advanced polymeric resin catalysts for the petrochemical industry. Faster process times, better yields, and higher product purity may be obtained by using a properly designed and purified catalyst. Purolite polymeric catalyst resins are supplied either completely water-swollen or dried to specification. When selecting a catalyst resin, consideration factors include process parameters and requirements, catalyst type, dry weight capacity, porosity and swelling/shrinkage properties.
