Chemical reaction kinetic perspective with mesoscopic nonequilibrium thermodynamics

Chemical reaction kinetic parameters are key factors to influence the NOx conversion in heavy duty diesel's SCR catalytic converter. Therefore the identification method of SCR chemical reaction kinetic parameters is studied in this paper. Based on the software AVL BOOST , SCR catalytic reaction model and its transient rate equations are established according to Eley-rideal mechanism. The identification method of kinetic parameters is studied applying AVL Design Explorer. The simulation model shows good agreement with experiment after identification. The result shows that the identification method is reasonable and feasible to ensure the reliability of catalytic converter model.

Spark Plasma

Chemical reaction kinetic model of hydrogen production from DME partial oxidation by plasma reforming was found. Mole fractions of main products of DME partial oxidation by spark plasma as the function of inlet gas flow rate were calculated at atmospheric pressure and ambient temperature. Comparing the results of calculation and experiment, the model was proved to be correct. The mechanism research was done by the method of sensitivity analysis and rate of production. The reduced mechanism which includes 16 species and 13 radical reactions was done. The calculation results of reduced mechanism and detailed mechanism were close. The result shows that the reduced mechanism can be used in chemical reaction kinetic calculation of hydrogen production from DME partial oxidation by spark plasma reforming.

Chemical Reaction Rates

The description of chemical reaction rates, in terms of the language of nonequilibrium thermodynamics, is compared with the conventional language of chemical kinetics. It is concluded that the formalism of nonequilibrium thermodynamics possesses considerable disadvantages, even in the regime where the rate is a linear function of affinity; this conclusion also holds for cases where chemical rates are coupled to diffusion processes. Some of the difficulties involved are illustrated using the experimental data of Nebeker and Pings (28).
