摘要: Hydrogen production by partial oxidation steam reforming of methanol over a Cu/ZnO/Al2 O3
cata lyst has been paid more and more attention. The chemical equilibria involved in the
methanol partial oxidation steam reforming reaction network such as methanol partial
oxidation, methanol steam reforming, decomposition of methanol and water-gas shift reaction
have been examined over the ranges of temperature 473-1073 K under normal pressure. Based
on the detailed kinetics of these reactions over a Cu/ZnO/Al2O3 catalyst, and from the
basic concept of the effectiveness factor, the intraparticle diffusion limitations were
taken into account. The effec tiveness factors for each reaction along the bed length were
calculated. Then important results were offered for the simulation of this reaction
process.
