【Abstract】 For multiple reaction system of methanol synthesis in the presence of Cu-based catalyst, hydrogenation reactions of CO and CO₂ are selected as key reactions. A diffusion model, taking CO and CO₂ as key components, is presented for the calculation of the intraparticle effectiveness factors of the two parallel key reactions over C301 Cu-based catalyst. Numerical solutions of the effectiveness factors ζco and ζco₂ are obtained and the reaction characteristics over the catalyst are discussed. The average absolute deviations between the values calculated from the model developed and experimental data for ζco and ζco₂ are 9.9％ and 23.9％, respectively. It can be considered that the model developed is simple and can be used to caluclated the effectiveness factors of parallel reactions.更多还原
