Abstract Electrostatic separation can be used to remove micron-sized catalyst particles from fluid catalytic cracking (FCC) slurry. In this study, simulations were performed with experimental parameters. The distributions of the electric field, slurry flow and particle motion were studied. According to the particle movement characteristics, an effective adsorption region was found in which the particles would be adsorbed on the surface of the fillers. The effect of the effective adsorption region on the electrostatic removal of catalyst particles from the FCC slurry was discussed. The size of the effective adsorption region was inversely proportional to the voltage and ionic carrier concentration. Under the same parameters, the size of the effective adsorption area and the motion of the particles were compared between the experiment and the simulation. The results showed that the numerical simulation results were in good agreement with the experimental results.

直流静电场下有效吸附区对催化裂化浆料去除催化剂颗粒的影响

摘要 静电分离可用于从流化催化裂化 (FCC) 浆液中去除微米级催化剂颗粒。在这项研究中，使用实验参数进行了模拟。研究了电场、浆液流动和颗粒运动的分布。根据颗粒的运动特性，发现了一个有效的吸附区域，在该区域内，颗粒将吸附在填料表面。讨论了有效吸附区域对催化颗粒从 FCC 浆料中静电去除的影响。有效吸附区域的大小与电压和离子载流子浓度成反比。在相同参数下，比较了实验与模拟的有效吸附面积大小和颗粒的运动情况。结果表明,数值模拟结果与实验结果吻合较好。
