Christy Catalytics pioneered the development of spherical inert catalyst bed support media with the introduction of PROX-SVERS® T-22 in 1952. Today, the PROX-SVERS® line of bed support media incorporates the widest available variety of alumina and silica-alumina ceramic formulas for use in virtually every type of fixed bed reactor in the petroleum refining, petrochemical, and gas processing industries. In fact, as a result, Christy has emerged as one of the world’s largest suppliers of engineered inert catalyst bed support media.
