摘要：
Abatement of formaldehyde by streamer corona discharge in multi point-to-plane reactor was studied experimentally. The removal efficiency of formaldehyde and the formation of products were evaluated as a function of the input concentration, the gas flow rate, the discharge polarity and mode. In addition, the effect of various pellet catalysts placed inside the discharge reactor was investigated. The chemical process and formed products were influenced by the processes of adsorption and plasma-assisted catalytic reactions. An improvement of the removal efficiency was observed with TiO(2) and gamma-Al(2)O(3) catalysts, especially at relatively high input energies and long-term operation.
