Catalytic Oxidation/Reduction Systems

The Catalytic Oxidation (CATOX) system utilizes a high activity, halogen tolerant catalyst bed to oxidize a wide range of organic compounds. CATOX is a well-established technology for the treatment of air streams containing hydrocarbons and is similar to systems used in catalytic converters in automobiles.

The CATOX system utilizes commercial CATOX technology developed and patented by Honeywell. The proprietary catalyst beds developed by Honeywell are optimized for efficient destruction of highly toxic organic compounds such as chlorinated VOCs and even chemical warfare agents such as nerve gas.

The catalyst used in the system was developed by Honeywell to treat agent-contaminated air streams by conditioning inlet air entering armored vehicles, helicopters, and airplanes.

CATOX technology is widely used in the treatment of waste environmental streams, such as contaminated air from soil remeadiation treatment of emissions from these applications is often complicated by impurities that can cause premature catalyst deactivation. As a result, Honeywell has developed specialized catalysts that can tolerate operation for processes that would deactivate first-generation catalyst systems. For example, although a first-generation catalyst such as alumina-supported platinum is deactivated by operation in the presence of hydrochloric acid, advanced halogen-tolerant catalysts can be used at a very high halogen level.

The CATOX system is designed to treat air streams generated from process buildings and effluent process-derived air. The treatment will oxidize all agents and toxic organic impurities present in the air streams, which will be subjected to the additional optional treatment with carbon. CATOX will destroy any toxic impurities and thereby eliminate or minimize toxicant loading on carbon beds. This process will greatly extend carbon life and may permit regeneration and reuse of the carbon beds.
