摘要

提出一种铁基氧载体（Fe3O4/FeO）化学链CO2重整CH4方法制备合成气。为评价该系统的性能，采用Aspen Plus软件对其进行过程模拟和热力学分析。以CH4转化率、CO2转化率、能源利用效率和产气氢碳比（H2/CO）为评价指标，得到系统的优化运行条件，并研究各操作参数（包括各反应器的温度和压力、氧载体甲烷比和CO2甲烷比）对系统性能的影响。结果表明：当系统处于优化工况时，得到CH4转化率为97.91%、CO2转化率为32.76%、能源利用效率为93.77%及产气氢碳比为0.93。该系统能有效利用CO2和CH4这两种温室气体获得较低氢碳比的合成气，利于二甲醚的高效合成。

Abstract

The chemical looping based on Fe3O4/FeO oxygen carrier was employed in the CO2/CH4 reforming to produce syngas. The process was simulated and analyzed using the Aspen Plus software to evaluate the performance of the system. CH4 conversion rate

CO2 conversion rate

energy efficiency and H2/CO ratio in the syngas produced were calculated and the optimum operation conditions were obtained. Sensitivity analysis of the system including reactor temperature and pressure

and Fe3O4/CH4 and CO2/CH4 ratios were also performed. It was found that CH4 conversion rate of 97.91%

CO2 conversion rate of 32.76%

energy efficiency of 93.77% and H2/CO ratio of 0.93 in the syngas produced were obtained at the optimum operating conditions in the system. The results indicated that the system could potentially bring about considerable conversion rates of CH4 and CO2. Furthermore

the produced syngas with a lower H2/CO ratio was suitable for the synthesis of dimethyl ether.
