摘　　要：在基于泡沫金属材料的微结构反应器中进行CO变换反应,考察CuZnAlZr催化剂的CO变换反应动力学。对实验数据进行最小二乘非线性回归,所得反应速率方程与实验数据吻合。利用所得到的动力学方程,针对典型醇类重整气组成,分析了为燃料电池提供氢源的CO变换反应器的体积功率密度,结果表明,CuZnAlZr微结构反应器是为小型燃料电池提供氢源的有效方案。Kinetics for CO shift reaction over CuZnAlZr catalyst was investigated in a metal-foam-based microstructured reactor.The rate equation,based on the non-linear least square regression analysis of the experimental data,well fitted in with the experimental data.Based on the typical gas stream from alcohol reforming and using the kinetic equation,an analysis was made on power density of the reactor for supply of hydrogen for fuel cells.The results showed that the microstructured reactor coated with the CuZnAlZr catalyst was an effective solution for supplying hydrogen to small fuel cells.
