在一搅拌反应器中，通过对在RaneyFe－Al合金抽滤过程中一定温度和浓度下Al生成量的分析，研究了其抽滤动力学，得到了各种参数对抽滤速率和比例的影响规律。这些参数包括抽滤温度、碱液浓度、RaneyFe－Al合金粒度和搅拌速度等。结果表明，抽滤过程第一阶段的动力学数据满足表达式：1－（1－x）1/3=kt，而后一阶段则可以用log（x/（1－x））=α·log（t／β）来表示，其中x是抽滤过程中的Al生成量，t是抽滤时间，参数α和β是常量。这里的反应动力学数据和活化能以初始反应速率为基础。结果还表明，在抽滤过程中生成的一部分Al存留在最后固体的内孔表面上。
In a stirred reactor, the kinetics of suction filtration was studied by analyzing the amount of Al formed at a certain temperature and concentration in the RaneyFe-Al alloy suction filtration process, and the influence of various parameters on the suction filtration rate and the ratio was obtained law. These parameters include suction temperature, lye concentration, RaneyFe-Al alloy particle size and stirring speed. The results show that the kinetic data of the first stage of the suction filtration process satisfy the following expression: 1- (1-x) 1/3 = kt, and the latter stage can be expressed as log (x / (1-x)) = (T / β), where x is the amount of Al produced in the suction filtration, t is the suction filtration time, and the parameters α and β are constants. The reaction kinetics data and activation energies here are based on the initial reaction rate. The results also show that a portion of the Al generated during the suction filtration remains on the inner pore surface of the final solid.
