Zeolites are widely used as catalysts in the refining of crude oil into finished petroleum products.  Zeolites can be uniquely tailored to specific applications.  Zeolites are also increasingly finding use in the production of petrochemicals, often replacing environmentally unfriendly catalysts.  Unlike more hazardous acid catalysts that have been used in the past, zeolites are non-hazardous, regenerable, and non-corrosive.  PQ Corporation has been actively involved in development and production of zeolite products for more than 25 years.  We continue to strengthen our reputation for quality by producing zeolites that meet our customers’ requirements and by providing services that fulfill their expectations.  If you would like to learn more about zeolite catalysts, go to
