PROX-SVERS® Catalyst Support Media

For over 50 years, PROX-SVERS® INERT CATALYST BED SUPPORT BALLS have set the benchmark of excellence for ceramic and alumina catalyst bed support balls. The PROX-SVERS® family of inert catalyst bed support balls has grown to protect all varieties of catalysts and adsorbents and consists of four products:

Ceramic Balls

T-38 PROX-SVERS® Ceramic Balls
T-38 PROX-SVERS ceramic balls, the premier silica-alumina inert catalyst bed support, easily meets and exceeds every specification under UOP's specification 3-37-0 for Type 1 and 2 inert catalyst balls. In fact, the proprietary formula of T-38 results in the highest physical properties of any clay ceramic world-wide.

T-86 PROX-SVERS® Ceramic Balls
T-86 PROX-SVERS, Christy's industrial grade ceramic balls, are recommended for low temperature (< 325º C) applications such as adsorbent beds and can be utilized as the standard refinery grade ceramic ball.

Alumina Balls

T-99 PROX-SVERS® Alumina Balls
T-99 PROX-SVERS alumina balls, composed of 99.5% sintered alpha-alumina with very low silica levels are an excellent choice for steam reforming in synthesis gas production or other high temperature applications where the presence of high water partial pressures can cause silica leaching.

The low level of other impurities such as iron, titania and alkalis make T-99 alumina balls an excellent choice for supporting adsorbents used to purify reactive monomers such as ethylene, propylene, and styrene.

The ultra low porosity, very high density and outstanding thermal shock resistance of T-99 alumina balls make them ideal for regenerative burner and filtering media for the metals industry.

T-46 PROX-SVERS® Alumina Balls
T-46 PROX-SVERS alumina balls are formulated specifically for the synthesis gas industries to prevent silica leaching in the presence of high water partial pressures. T-46 has an excellent 50 year track record of service in the ammonia industry.
