铁基氧载体化学链CO2重整CH4方法制备合成气
Chemical looping CO2/CH4 reforming using Fe-based oxygen carrier for syngas production
摘要
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.关键词
