【Abstract】 The steady-state kinetics of deep oxidation of methanol on Pt/Al2O3 catalyst has been investigated by the flow recirculation glass reactor and it was found to obey the L-H model. The parameter values of the kinetic equation were estimated by the method of orthogonal design. The adsorption heats of methanol, oxygen and carbon dioxide and the dependence of the amount of methanol adsorbed over the catalyst on the residence time were determined by the pulse method. Oscillatory phenomenon of the deep oxidation has been observed.更多还原
