摘　　要：生物甘油催化重整技术为制氢工业的发展提供了广阔的前景,而二氧化碳吸附强化重整因能降低能耗和促进氢气产量被广泛关注。基于欧拉-欧拉双流体模型,结合化学反应动力学,对流化床反应器中二氧化碳吸附强化甘油重整过程开展了数值模拟,评估了催化剂和吸附剂颗粒在反应器中的流动行为,分析了操作压力对气体产物分布的影响。结果表明,催化剂和吸附剂在床中形成了典型的内循环流动结构,压力的增加会促进吸附反应,但在一定程度上减少了氢气的纯度。The glycerol catalytic reforming provides a promising way for hydrogen production industry.The carbon dioxide sorption-enhanced reforming has attracted more and more concerns owing to its advantage of low energy consumption and high hydrogen prodution.Under the Eulerian-Eulerian framework integrated with chemical reaction kinetics,the sorption-enhanced reforming of glycerol in a fluidzed bed reactor is simulated.The flow behaviors of catalyst and sorbent in reactor are examined.The effect of operating pressure on gas products is analyzed.The results show that the internal circulation flow structure formed by catalyst and sorbent in reactor can be observed.The increase of pressure can promote the sorption reaction,whereas reduces the hydrogen purity.
