The operating range suitable for three-phase reaction was obtained and a mathematical model established. The results show that MSB formed by fine magnetizable powder and fliudizing flow can be operated stably in a wide range. MSB has three kinds of regimes: particulate, chain, and magnetically condensed. In these regimes, the chain regime is the best for three-phase reaction. When Ni-RE-P catalyst particles mixed with some iron powder, magnetically stabilization is easily achieved; therefore, it is possible that NiRE-P catalyst can be controlled in the bed for reaction more easilly if adding certain percentage of iron powder.

研究结果表明：细粉铁磁性颗粒形成的磁稳定床可在较宽流速范围内稳定操作，该磁稳定床有三种操作状态：散粒状态，链式状态和磁聚状态，其中有利于进行气液固三相反应的操作状态是链式状态；当磁稳定床在最小流化速度和带出速度之间操作时，床层处于链式状态；最小流化速度和带出速度可用（1-24）、（1-25）、（1-27）、（1-33）式计算；弱软磁性Ni-RE-P非晶催化剂中混入定量铁粉颗粒后便可形成磁稳定床，因此利用混入铁粉颗粒在外加磁场作用下控制弱磁性非晶催化剂颗粒进行反应的方法是可能的。
