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 Cr2 O3催化剂MOR 6 7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 .2MPa～ 0 .
The coupling of oxidation of methanol (a strong exothermic process) with the steam reforming reaction(a high endothermic process) is an attractive route for H 2 production in terms of energy minimization. Analysis showed that the radial reactor is the most attractive configuration for on board H 2 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.
