Purification by catalytic oxidation

Most industrial and power applications produce off gases that are harmful to health, the environment or have global warming potential, such as CO2, CO, hydrocarbons etc. As the world is pledging to reduce global warming to below 1.5° C compared to pre‐industrial levels, removing or re‐using these gases is crucial to achieve this target.

Catalytic oxidation is a facile and economic process to remove a wide range of impurities from industrial gas streams as part of feedstock, in-process or effluent purification. The versatility of the chemistry and its application, combined with the Johnson Matthey’s long-standing experience in precious group metal (PGM) catalysis, places catalytic oxidation at the heart of the purification needs in a decarbonising world.

Johnson Matthey’s PURAVOC^TM technology provides catalytic oxidation solutions to remove volatile organic compounds (VOCs), oxygen, hydrogen and carbon monoxide.

PURAVOC alumina-supported PGM fixed bed catalysts are specially designed to oxidise individual or complex gas impurities to very low levels, at temperatures lower than thermal processing and with minimal intervention. As a result, PURAVOC catalysts can achieve long and dependable bed life at reduced OPEX, making this a very economical solution.

Capitalising on the PURAVOC brand's long history, we have extended our portfolio with dedicated and improved catalysts for emerging applications.
