【Abstract】 The oxidation of CO in a microreactor was catalyzed by Pd/SnO₂ for a gas system with CO :O2 : N2=1 :1: 8. The kinetic equation of the reaction has been derived on the principle of the microreactor. The rate equation R=kC-1coCo2 of the reaction was obtained at various constant temperatures within the range 30⁸0℃ by measurign some experimental data such as the gas flow, the conversion efficiency of CO and space velocity of the gas mixture. With the Arrhenius equation,the activated energy of E=61:596kJ.mol-1 has been obtained by linear regression of the data. The correlation coefficient γ of the regression equation is 0.998 6.更多还原
