甲醇自热重整制氢反应分析

摘要

甲醇自热重整制氢反应是车载燃料电池氢源的理想方式。本文应用ZnO/Cr2O3催化剂MOR-67上的宏观动力学，模拟分析了甲醇自热重整制氢反应器，合适的反应器为绝热径向反应器。对于本反应器一维拟均相模拟结果表明：适宜的水/醇比为2（常压）或3（低压）；压力：0.2 MPa～0.3 MPa。%The coupling of oxidation of methanol (a strong exothermic process) with the steam reforming reaction(a high endothermic process) is an attractive route for H2 production in terms of energy minimization. Analysis showed that the radial reactor is the most attractive configuration for on-board H2 generation. Using a one-dimensional homogeneous model, the paper discussed the performance of this self-evident process. The optimal rate of water to methanol and pressure are 2 (under normal pressure) or 3 (when P>1?atm) and 0.2?MPa～0.3?MPa, respectively.
