    Abstract: Hydrogen generation from steam reforming of
    methanol (SRM) with a CuO/ZnO/Al2O3 catalyst
    was investigated in the study; particular emphasis was placed on the reactions of SRM exposed to an environment with microwave irradiation. By virtue of the double absorption of microwaves by both the reagents and the catalyst, the experiments
    suggested that the SRM could be heated and
    triggered rapidly within a short time, and the methanol conversion from SRM with microwave heating was high compared to that with conventional heating. The obtained results also indicated that, when the reaction temperature was as high as 250°C, thermodynamic equilibrium governed the SRM, whereas the reaction was kinetically controlled for the temperature lower
    than 250°C. Contrary to Le Châtelier's principle, it was noted that an increase in S/C ratio decreased methanol conversion. This can be explained by the fact that water absorbs microwave irradiation stronger than methanol.
