| The pollution of NOx is a global issue. Except for the emission of a lot of soot particles NOx and SO2 during combustion of coal, the burning of coal lets out volatile organic compounds. The amount of volatile organic compounds is smaller than NOx and SO2, but it is a heavy toxicity. It is becoming a more and more heavy issue.This paper simulated the process of removing of NOx by infusing NH3. Simulating the process at different temperature, different NH3 concentration and different gas velocity, the conclusion is as follows:(1)Temperature has a larger influence on the reaction, NH3 reduces as the temperature rise, and the highest efficiency happens at when the temperature is in 800-900 centigrade degree.(2)NO concentration diminishes with the rise ofβ, however NH3 concentration has little change with the rise ofβ, but needs longer reaction time.(4)At the same condition, the residual concentration of NO is higher in the Cylindrical Shear Flow Reactor than that in the Planar Shear Flow Reactor, and the value is lowest in the Plug Flow Reactor.Subsequently, the present paper simulated the process that removing of VOCS by adding hydrogen peroxide to the gas, and studied the process at different gas temperature, concentration of hydrogen peroxide and gas velocity.The simulated gas is premixed and ignores the affection of mixing process. By analyzing the results, the conclusion is drawn out, and as follows:(1)The temperature has an obvious affection on the results, the temperature should be higher than 1073K considering the mole fraction of C6H6, H2O2, C6H5O at the reactor outlet.(2)Whenβ=4.0-6.0, the mole fraction of C6H6 and C6H5O may at a lower concentration.(3)A mount of OH radical that is produced in the process accelerate the changing of C6H6.
