Copper Chromium

Chromium catalysts have been used for oxidation of volatile organic compounds (VOCs) and carbon monoxide for over 40 years. They are highly active, competitively priced, and tolerant to low to moderate concentrations of sulfur and silicon-containing compounds.

 

Specifications

 

High Copper

The high copper catalyst enhances VOC oxidation at very low temperature and it is often used in combination with the manganese oxide catalyst. It can also be applied in decomposition of ozone emission and ozone-assisted catalytic oxidation of VOCs at room temperature.

Manganese-based Catalysts

Catalysts

All Catalysts • Benefits • Specs

Developed in the 1980s, the manganese oxide catalysts are made via a proprietary thermal activation process that makes the resulting catalyst highly active and resistant to halogens and extreme heat.

Benefits

  • Hundreds of commercial applications worldwide in wood, chemical, packaging and other industries
  • Reliable and low-maintenance catalysts that combine high activity and many years of service, at a competitive price
    • 8+ year service time in wood industry and 5 years and longer in chemical industry and other applications
  • Produced in a variety of shapes and sizes to fit the requirements of each application
  • Particularly effective in regenerative catalytic oxidizers (RCOs) and for converting regenerative thermal oxidizers (RTOs) into RCOs. Smaller size catalysts are used in recuperative oxidizers or afterburners operated with fixed or fluidized beds
  • Designed to operate in a wide temperature range, up to 700 °C (~ 1,300°F) long-term, with short excursions up to ~ 900 °C (~ 1,650 °F) withstanding temperature surges during burnouts of RCO ceramic media
  • Tolerant of many common catalyst poisons including chlorine, bromine, phosphorus, heavy and alkali and alkaline-earth metals and can be easily regenerated after poisoning via on-line bake out
  • Non-hazardous material, safe for handling, loading, unloading, utilization, and disposal in common landfills

Catalysts

Catalysts

We offer unique transition- (or base-) metal catalysts for VOC oxidation that have relatively low cost while providing excellent performance in terms of catalytic activity and service time.

During the past thirty years, our catalysts have been successfully used across a broad range of applications including composite board, chemical, electronics, and packaging industries.

Our product line includes catalysts based on alumina supported oxides of manganese, chromium, copper and others. The catalysts loaded in bulk beds are made of different shapes and sizes, each fitting a specific regenerative and recuperative oxidizer and/or catalytic afterburner.

In addition to the bulk bed VOC removal catalysts, we supply precious-metal catalysts supported over structural monoliths, carbon-alumina adsorbents and vanadium catalysts for NOx removal via selective catalytic reduction.
