千瓦级 PEMFC 甲醇水蒸气重整制氢过程热力学模拟
Thermodynamic Simulation for Hydrogen Production in the Methanol Steam Reforming System of Kilowatt PEMFC
摘要
Abstract
The thermodynamic simulation analysis for methanol steam reforming hydrogen production system of kilowatt proton exchange membrane fuel cell was researched by Aspen Plus software.The influences of water to methanol mole ratio (0.8~1.6),reaction temperature (140~400 ℃),and pressure (101.325~506.625 kPa)on methanol steam reforming process were investigated.The results show that the methanol equilibrium conversion and CO mole fraction increase when the temperature is raised,while the H 2 mole fraction decreases at the same time.The equilibrium conversion of methanol decreases with pressure increasing,but the pressure has little effect on the mole fraction of H 2 and CO.The equilibrium conversion of methanol is improved with the water to methanol mole ratio raising.However,a large number of water vapor will increase the load of the system and lower the thermal efficiency.Therefore,the appropriate range of water to methanol mole ratio is between 1.2 and 1.4.It can be found that H 2 mole fraction is 64.27% and CO content is below 10 -5 ultimately through simulation of the hydrogen source system,which can provide hydrogen source for kilowatt proton exchange membrane fuel cell.关键词
