摘　　要：在质子交换膜燃料电池 (PEMFC)移动氢源———甲醇氧化重整制氢自热体系中 ,研究了反应器构型对产氢能量效率和床层内“热点”温度的影响 ,得到了反应器设计准则 。The effect of reactor configuration and technical parameters on the gross heat efficiency and 'hot spot' temperature was investigated in an autothermal operation process of methanol partial oxidation based on the balance of mass and energy balance as well as kinetics of the reactor. The conversion of methanol, productivity of hydrogen and the gross heat efficiency increased with the decrease of height/diameter ratio of the reactor when the same amount of catalyst was used, so the catalyst effective index was enhanced by this means. Furthermore,for the same gross heat efficiency,a lower amount of oxygen or air was needed when the height/diameter ratio was relatively small, which lead to the decrease of 'hot spot' temperature. In order to make the 'hot spot' temperature even lower, a reactor with multi-inlets could be used.The 'hot spot' temperature dropped greatly when oxygen was input by two inlets or more,and only trivial loss of conversion and hydrogen productivity was observed. Therefore, the principle of reactor design was obtained, and the suitable configuration of the reactor, such as radial flow reactor and inorganic reactor was proposed.
