RMP - Criterion Catalysts

Pittsburg, CA

Criterion's Pittsburg facility manufactures a variety of catalysts for the oil and styrene manufacturing industries. Products manufactured are dry solids, containing alumina oxide, iron oxide, and other metals. The primary products are hydrotreating catalysts, an aluminum oxide based catalyst for petroleum refineries, and dehydrogenation catalyst, and an iron oxide based catalyst for the manufacturing of styrene. Aqueous Ammonia is used as a raw material in select catalyst manufacturing and is also used in selective catalytic reduction (SCR) for the reduction of nitrogen oxides emissions in the furnaces.
