Specialty Zeolites

Zeolyst International has been specializing in zeolite powders, catalysts, and adsorbents since 1988, emerging as a global leader for both commercial and specialized zeolites. We combine the zeolite product development and manufacturing skills of our parent companies, PQ Corporation and CRI International, Inc., a member of the Royal Dutch Shell Group of companies, into a single entity. Our sister company, Criterion Catalyst Company, extends our capabilities by offering a complete line of quality catalyst products, advanced process technology, and experienced technical service.

A wide variety of commercial zeolite products and our capability to customize zeolites for specific applications give you the flexibility to optimize your process for maximum success. Our materials have been used as catalysts in refinery, petrochemical, and fine chemical processes, as adsorbents and catalysts in environmental applications, as molecular sieves in size separation applications, and as multifunctional materials in a variety of applications.

Aggressive investment in research, development, and capital improvements helps us keep pace with our customers' developing needs. The resulting worldwide network of manufacturing plants, research and development laboratories, and leading technical specialists makes us a world-class supplier of zeolite products and a valued resource for our customers. It's easy to understand why many major international companies have chosen Zeolyst International as a partner for their strategic product and process development programs.
