Gas Treatment by Catalytic Ozone Oxidation



In recent years, indoor air quality has become an important issue in Hong Kong, China and in many other countries. Numerous indoor sources emit a low concentration of volatile organic compounds (VOCs), which cause adverse health effects such as allergic reactions, tiredness, and even cancer. Considerable effort is spent on aligning industrial practice with government regulatory requirements. The adsorption based air purification technology transfers the VOCs to another phase rather than eliminating them, thus leading to the problem of additional disposal and waste treatment.

Plasma-assisted catalytic oxidation (PACO) as an energy-efficient technology for air purification
Compared with conventional air pollution control techniques such as thermo-catalytic oxidation, PACO is more appropriate for air purification because it is more energy efficient and works at a lower reaction temperature (25-150 oC). The advantages of the PACO technology are: 1) low operating temperature; 2) intermediate species are adsorbed in the substrate; 3) long operational lifetime of the substrates.
