RADIATION INDUCED SCAVENGING OF NO_x, SO_2, H_2S FROM EXHAUST GASES

摘要

The theoretical model of exhaust gases radiation induced oxidation was developed. NO, SO_2 and H_2S concentrations curves vs dose calculated by use of this model for mixtures containing N_2 (80.5%), O_2 (11%), H_2O (8.4%), NO (100-600 ppm), SO_2 (150-500 ppm) and H_2S (300-1000 ppm) have been obtained. It has been shown that NO and SO_2 conversion reactions with acids formation go simultaneously with oxidizing reaction of H_2S giving SO_2 as an intermediate substance. These processes were evaluated for different initial concentrations of NO, SO_2 and H_2S. Data established by our simulation calculations show that the electron beam process can be judged as a promising technology for simultaneous removal of SO_2, NO and H_2S from exhaust gases.
