Abstract:To improve activity of traditional Vanadium-titanium SCR (Selective Catalytic Reduction) catalyst under low temperature condition, Pre-oxidation technology is proposed in this research. In this paper chemical reaction kinetics which includes chemical reaction mechanism, reaction rate and so on is studied, and especially chemical reaction rate equations on "Standard-SCR Reaction" and "Fast-SCR Reaction" are deduced. By the bed test of YZ4DB1-30 diesel engine, it has been found that the activity of Urea-SCR cata… Show more
