| 摘 要： | 气固并流顺重力场与逆重力场流动形成了迥然不同的流态化机制.与提升管相比,下行床具有气固速度及颗粒浓度径向分布较均匀、气固停留时间短而一致等特点,其流型更接近平推流.

| Abstract: | The fluidization mechanism of gas - solid concurrent with gravity field is disparate with that of gas -solid countercurrent with gravity field. Comparing with riser- reactor, downer - reactor has many advantages, such as well - distributed radial gas - solid velocity and particle concentration, short and uniform gas - solid resident time,and the flow style is more close to plug flow. |
