Chemical Kinetics and Oxidation Mechanisms Between O₃ and NO _x /SO₂/Hg

Abstract

Dynamics simulations and sensitivity analysis were performed by using the SENKIN module ^[1] in the CHEMKIN software package. The reaction rate of the branched-chain reaction varies under different conditions. Thus, to evaluate the chemical kinetics effect on reactions of ozone and NO _x /SO₂/Hg, varying various parameters to obtain a more correct choice of elementary reaction and kinetics parameters and a more precise modelling of reaction progress is defined and there related information is gathered during the modelling process. Meanwhile, the crucial factors, which comprise the reaction rate sensitivity, density sensitivity, and temperature sensitivity and have a significant effect on the reaction, are attached much more significance. Through sensitivity analysis, the limit rate reaction in the chemical reaction system can be obtained. Furthermore, relationships between various reactions and the importance of these interrelated reactions in the entire system can also be analyzed. The novel chemical kinetics mechanisms between ozone and flue gas components are to be uncovered finally.
