To investigate the effect of temperature on the removal of acetaldehyde, ammonia and trimethylamine gases from N2 using electron attachment reactor. The target gases are malodorous gaseous components emitted at high temperature from a crematory furnace. Since the emitted gases from a crematory furnace consist of O2 and water vapor, the factors investigated are inlet gas concentration of the target gases, percentage of coexisting O2 and the concentration of water vapor in the N2 gas stream. To understand the effect between the target gases, the experiments are carried out both for the separate removal of target gases and the simultaneous removal of 2 and 3 target gases. The experimental results reveal that, regardless of the temperature, the lower the inlet concentration, the higher the removal efficiency becomes. It is found that the presence of oxygen enhances the removal efficiency of the target gases both in the separate removal of target gases andthe simultaneous removal of 2 and 3 target gases. The presence of water vapor enhances the removal efficiency of the target gases from N2 at low temperature but slightly retards it at high temperature. However, the presence of water vapor in nitrogen and oxygen mixture has adverse effect on the removal efficiency. The effects between the target gases on the simultaneous removal of 2 and 3 target gases are investigated. It is found that in the case of the simultaneous removal of 3 target gases, the number of acetaldehyde, ammonia and trimethylamine gas molecules captured by an electron are higher than in the case of simultaneous removal of these 2 target gases. Furthermore, the application of two independently operated corona-discharge reactors in series is shown to have a good promise for enhancing the removal efficiency and minimizing the generation of byproducts. It is found that the effluent NOX is reduced from 50 ppm to 20 ppm and O3 is removed completely
