An internally circulating fluidized bed (ICFB) has been applied in various industrial processes owing to its potential in the reduction of heat loss and compact size. In this work, the sorption-enhanced reforming process in the ICFB is investigated. The dense discrete phase model (DDPM) is employed to evaluate the performance of catalyst-sorbent bi-functional particles, considering the particle size distribution. The results demonstrate that the utilization of bi-functional particles can significantly increase hydrogen production. The impacts of operating parameters including solid loading and regenerator velocity on solid circulation rate and gas leakage are examined. It is found that the gas leakage between reactors is increased by 46.6% when the regenerator gas velocity varies from 1.8 m/s to 2.4 m/s so as to weaken the hydrogen yield.

内部循环流化床（ICFB）由于具有减少热量损失和紧凑尺寸的潜力，已被应用于各种工业过程。在这项工作中，研究了ICFB中吸附增强的重整过程。考虑到粒度分布，采用致密离散相模型（DDPM）评估催化剂-吸附剂双功能颗粒的性能。结果表明，利用双功能颗粒可以显着提高氢气产量。研究了包括固体负荷和再生器速度在内的运行参数对固体循环速率和气体泄漏的影响。发现当再生器气体速度从1.8m / s变化到2.4m / s时，反应器之间的气体泄漏增加了46.6％，从而削弱了氢气的产生。
