Catalyst Extrusion Equipment

Diamond America designs and builds custom catalyst extruders to form catalysts, or ceramic catalyst carriers, for the petrochemical, DeNOx and water purification industries.

Properties of Catalysts

Catalysts are substances that assist in chemical reactions without being consumed by them. They may be impaired or destroyed by the process, by dissolving or changing state, but they do not take part in the main reaction.

Common catalysts include the oxides of base metals, such as tungsten, vanadium or molybdenum oxides, or zeolites or other precious metals.

Application Notes

Extrusion is still the preferred, most cost effective solution for rapidly producing large quantities of catalysts, especially when intricate configurations are needed. Diamond America’s modular catalyst extrusion equipment, including application-specific dies mold the material into tubes, rings, wheels, rods or any shape with the required surface finish characteristics.

Twin feed packers and screw design promotes efficient, positive feeding and eliminates build-up of residual material in the feed hopper, preventing die-clogging.

Expertise in the catalyst extrusion industry allows Diamond America to produce custom equipment that can form even the most difficult to process catalytic materials at peak efficiency for high volumes, in continuous production. Thorough mixing action through excellent screw and barrel design combines with highly accurate process control to ensure consistent composition and sizing of the final catalysts.

Catalyst Example

Extruded honeycomb catalysts are used in the DeNOx process and selective Catalytic Reduction (SCR) for Nitrogen Oxide reduction.

The extrusions are made from ceramic materials that are used as a carrier for the active catalytic components and their honeycomb structure presents a large surface area over which the reaction can take place.
