| 摘 要： | 本文提出以Fe2O3为载氧体、以CaO捕集CO2的生物质化学链气化系统,利用Aspen Plus软件对该系统进行了模拟,以合成气组成（干基）、合成气氢碳比、含碳产物的碳摩尔分布、冷气效率及收率等为系统性能评价指标,重点分析了燃料反应器温度（TFR）、载氧体Fe2O3与生物质碳摩尔比（Fe2O3/C）、水蒸气与生物质碳摩尔比（Steam/C）、CaO与生物质碳摩尔比（CaO/C）等系统参数对固体生物质化学链气化系统的影响。结果表明,在TFR = 825℃、Fe2O3/C = 0.5、Steam/C = 0.71和CaO/C = 0.26条件下,合成气制备系统性能较优,合成气中H2和CO2含量分别为55.2%和15.4%,氢碳比为1.93,冷气效率为78.2%,被CaCO3捕集的生物质碳为18.2%,收率（湿气基）为1.95 Nm3/kgbiomass,其中合成气中H2和CO收率为1.24 Nm3/kgbiomass。 |

| Abstract: | A model of biomass chemical looping gasification coupled with in situ CO2 capture by CaO was proposed by using Fe2O3 as oxygen carrier and simulated with Aspen Plus software. The effect of fuel reactor operation parameters on bio-syngas production performances were investigated, including fuel reactor temperature (TFR), the mole ratios of oxygen carrier to carbon in biomass (Fe2O3/C), steam to carbon in biomass (Steam/C) and CaO to carbon in biomass (CaO/C). The evaluation index includes syngas composition, H2/CO ratio, carbon distribution in the products, gas efficiency, syngas yield and so on. The results showed that H2 content of 55.2%, H/CO ratio of 1.93, gas efficiency of 78.2%, CO2 content of 15.4%, and syngas yield of 1.95 Nm3/kgbiomass (the yield of H2 and CO in syngas was 1.24 Nm3/kgbiomas) were obtained under the optimized condition (TFR = 825oC, Fe2O3/C = 0.5, Steam/C = 0.71, and CaO/C = 0.26). |
