NO removal in the process of adsorption non-thermal plasma catalytic decomposition

The interesting process of adsorption NTP catalytic decomposition (ANCD) was used for NO removal without external heating. NO removal by NTP alone, NTP assisted catalytic decomposition (NCD) and ANCD were each studied for comparative purposes. The energy efficiency, NO removal efficiency and discharge power of these processes were investigated. Compared with the other two processes, outstanding experimental results were achieved by the ANCD process. Using this process, three different catalysts were also investigated. The results showed that the adsorption properties of the catalyst play a key role in the ANCD process. In addition, the influence of NO concentration on the conversion of NO was not appreciable. When the flow was too large, the residence time of pollutants in the catalyst decreased, resulting in a reduction in its adsorption capacity for pollutants and a decrease in the NO conversion and energy efficiency.
