摘要

以模拟汽车尾气供热的甲醇水蒸气重整（MSR）制氢反应为研究对象，设计了集余热加热与MSR制氢反应于一体的肋式微反应器，考察了反应器进口热风速度、温度，反应物进口速度、温度、水醇比及顺逆流情况对MSR制氢过程的影响。计算结果表明，逆流、水醇比1.3、热风进口速度1.1 m/s、温度773 K、反应物进口速度0.1 m/s、温度493 K为该反应过程的最佳工况参数，此时甲醇转化率为99.4%，模拟汽车尾气余热的热效率为28%，反应器出口氢气的体积分数为69.6%。研究结果对开展余热综合利用及发动机尾气重整制氢掺氢燃烧的研究有借鉴意义。

Abstract

The process of methanol steam reforming (MSR) for hydrogen production heated by simulated exhaust heat was studied. Radial fin reactor was designed with waste heat recovery. The effects of simulated waste heat air inlet velocity and temperature

reactant inlet velocity

temperature and water methanol ratio

reactant and heated air co-current and counter current flow conditions on MSR process were investigated. Results showed that the optimum operation condition of this reactor is that the reactant and heated air operates as co-current flow

water methanol ratio sets as 1.3

inlet heated air velocity and temperature keep as 1.1 m/s and 773 K

inlet reactant velocity and temperature maintains as 0.1 m/s and 493 K. Methanol conversion reaches 99.4% and thermal efficiency of simulated exhaust heat reaches 28%

reactor outlet hydrogen volume fraction attains 69.6%. The results can give some reference for waste heat utilization and exhaust heat reforming for hydrogen production

combustion blended with hydrogen.
