Microwave-Induced Catalytic Removal of Hazardous Gases

Abstract

A microwave-induced catalytic removal device was designed and set up for studying removal of hazardous or toxic gas from contaminated air. Catalytic oxidative Removal ratios of several hazardous gases of VOCs, CO and H2under microwave field were tested. Results suggested that structure of hazardous gas and catalyst type were main factors affecting the removal efficiency of hazardous gas. Oxidative catalyst contributed to removal of reductive gas. In addition, the flow rate also affected the removal efficiency.
