【Abstract】 Ab initio MP2 method was performed to study the reaction mechanism and kinetics of mercury chloride series during the process of coal combustion. Seven channels were detected by calculations, the geometric configurations of reactants, products, intermediates and transition states were optimized and their energies were calculated at QCISD(T)/SDD level. Besides, we used the classic transition state theory to calculate the rate constants of the seven channels. Compared with the experimental values, the results show that the rate constants are in good agreement with experimental data.更多还原
