【Abstract】 The intrinsic reaction rates of the methanol decomposition in CO-H₂-CO₂-CH₃OH system under atmospheric pressure over C301 cupric-basedcatalyst have been measured.The parameter estimation of the intrinsickinetic model of the power type for methanol decomposition is performed.It is obtained that the kinetic equation of the methanol decompo-sition isR_m=-（dN_m）/dW=0.9525×10¹⁰exp（-24840/R_gT）p_CO^-0.30p_H2^-0.15p_m^0.65p_CO2^0.45 mol/g·hThe ranges of temperatures and compositions of gases chosen in experi-ment are analogous to that of industrial methanol production.This researchshows that carbon dioxide plays an active part in the methanol decompo-sition reaction and the shift reaction approachs to chemical equillibrium.更多还原
