A three-dimensional numerical model of a methanol steam reforming micro-channel reactor for hydrogen production based onCu/ZnO/Al2O3 catalyst was established. The effects of different inlet mass flow rate, reaction temperature and steam to carbonratio (S/C) on the mass change of each component, chemical reaction rate and hydrogen production performance of microchannelreformer were studied. The results show that with the increase of inlet mass flow rate, the mass fraction of CH3OH atthe outlet of reforming channel increases gradually, and the methanol conversion rate decreases gradually. The mass fractionof CO at the outlet of reforming channel decreases gradually, and the CO selectivity decreases gradually. With the increase ofreaction temperature, the mass fraction of CH3OH at the outlet of reforming channel decreases gradually, and the methanolconversion rate increases. The mass fraction of CO at the outlet of reforming channel increases rapidly, and the CO selectivityincreases rapidly. With the increase of S/C, the methanol conversion rate increased and the CO selectivity decreased. In thisstudy, the influence of reaction conditions on methanol reformer was obtained, and the reasons behind it were clarified, whichprovided more valuable insights for the operating conditions of hydrogen production from MSR.
