Abstract
The effect of C3H6 on the deNO(x) activity of CuZSM5, FeZSM5 and V2O5/TiO2 catalysts by NH3 has been examined. The catalytic NO removal activity decreased by the continuous inclusion of C3H6 into the reactor feed gas stream. The higher the feed concentration of C3H6, the more severe the retardation of the catalyst activity. The primary cause for the inhibition is the competitive adsorption of NH3 and C3H6 onto the catalyst surface and the useless consumption of NH3 by the side reaction, including the NH3 oxidation and ammoxidation reactions during the course of NH3/SCR reaction with C3H6.
