研究了循环流化床中催化剂颗粒团簇对甲烷干重整反应性能的影响。预测了通过静止催化剂簇的流动行为和化学反应。采用Rh/Al 2 O3催化剂颗粒的简单二维模型，得到了气相温度和气体组分浓度的分布。数值结果表明，催化剂颗粒在团簇中的重整反应速率远小于单独催化剂颗粒在流中的重整反应速率。由于催化剂颗粒聚集，H2/CO摩尔比增加。考察了气体温度、入口气速和反应器压力对重整反应的影响。
A study was undertaken to determine whether the performance of dry methane reforming could be affected by catalyst particle clusters in circulating fluidized bed reformers. Flow behavior and chemical reactions through a quiescent catalyst cluster were predicted. The distributions of gas temperature and concentrations of gas species were obtained using a simple two-dimensional model with Rh/Al2O3catalyst particles. Numerical results show that the reforming reaction rate on catalyst particles in the cluster is much smaller than the rate on isolated catalyst particle in the stream. The molar ratio of H2/CO is increased due to catalyst particle clustering. The effects of gas temperature, inlet gas velocity and reactor pressure on reforming reactions are also investigated.
