title: [Catalytic oxidation of two-component VOCs and kinetic analysis ].
abstract: Catalytic oxidations of two-component volatile organic compounds (VOCs) toluene and chlorobenzene were investigated under microwave heating and tube furnace heating, respectively, and reaction kinetics were analyzed in this paper. The research indicated that competitive adsorption between toluene and chlorobenzene reduced their removal efficiencies by 3% -12% as compared to single component. 'Hot spot effect' and 'non-thermal effect' under microwave irradiation obviously enhanced conversion efficiencies of VOCs, especially, the chlorobenzene removal was increased by 31% -38%. Moreover, reaction temperature and energy consumption were both reduced under microwave heating. The dynamic calculations showed that microwave heating decreased the activation energies by 2 146 J. mol-1 and 1 450 J mol-1 for toluene and chlorobenzene, respectively, as compared with tube furnace heating. Meanwhile, microwave heating enhanced the reaction rate constants of chlorobenzene and toluene to about 35 times and 6 times of that of tube furnace heating.
