Abstract The catalyst solid particles in fluid catalytic cracking slurry (FCCS) can be removed by electrostatic separation. In this study, on the basis of the “effective contact point” model proposed by the authors for the nonuniform electric field (Li et al., 2019a [1]), the corresponding “effective contact point” model was proposed when the applied original electric field was uniform. Then, the adsorption properties of particles under the action of a uniform electric field and a nonuniform electric field were simulated and compared. The results showed that the “effective contact point” model in uniform electric field was correct, and the adsorption of the particles in the nonuniform electric field was better than that in the uniform electric field. The simulation of the electric field strength at the contact point of ellipsoidal fillers showed that the adsorption capacity of ellipsoidal fillers on particles was higher than that of the sphere fillers within a certain range.

静电场去除FCCS中催化剂颗粒的微观机理研究

摘要 流化催化裂化浆液（FCCS）中的催化剂固体颗粒可以通过静电分离去除。本研究在作者针对非均匀电场提出的“有效接触点”模型（Li et al., 2019a [1]）的基础上，提出了相应的“有效接触点”模型。电场是均匀的。然后，模拟并比较了均匀电场和非均匀电场作用下颗粒的吸附性能。结果表明，均匀电场下“有效接触点”模型是正确的，非均匀电场下颗粒的吸附效果优于均匀电场下。
