摘要
用硅烷化试剂对改性聚苯醚(PPO)颗粒进行表面脱活性处理,发现其流化性能得到改善,同时水在颗粒间流动的阻力略有减小。
Solid surface characteristics which affect liquid fluidization quality may be presented in terms of surface energy. Thus, PPO particles are coated with DMDS, a silicane,to eliminate surface activation. Liquid fluidization experiment show fluidization homogeneity improved and fixed bed pressure drop decreased owing to the weakened particle-particle,particle-fluid interactions.
