摘要：
FeO/Fe3O4作载氧体，以链式反应器构建煤气化氢电联产系统，用ASPEN PLUS软件对系统的性能进行了模拟。研究链式反应器温度、水蒸汽转化率对系统性能的影响，并对系统流程进行了火用分析。结果表明，系统生产的H2的纯度高，可达99.9%，CO2 近零排放； 当水蒸汽反应器在815℃、水蒸汽转化率为37%时，系统的净效率达到58.06%；水蒸汽转化率对系统性能影响较大，由28%增加到41%时，系统的效率由53.17%增加到58.33%；系统的火用损主要集中在气化炉和余热锅炉部分。

Abstract:
Using FeO/Fe3O4 as an oxygen carrier, a carbon-free co-production system of hydrogen and electricity with chemical-looping reactors was proposed. The performance of the new system was investigated using ASPEN PLUS software. The influence of chemical-looping reactor's tempe- rature, steam conversion rate on the system performance was simulated and the exergy performance was also discussed. The results show that the purity of H2 production reaches 99.9% and CO2 can be separated. The system efficiency is 58.06% assuming steam reactor at 815℃ and the steam conversion rate of 37%. The system efficiency is affected by the steam conversion rate obviously, rising form 53.17% to 58.33% with the increase of steam conversion rate from 28% to 41%. The exergy losses of the whole system are mainly taken place in the process of gasification and heat recovery steam generator (HRSG).
