Transport phenomena are investigated which are involved in the electrokinetic remediation process used for removing vanadium from deactivated catalysts from oil catalytic cracking that are currently allotted to cement plants and class‐I landfills. Variables such as the concentration of electrolyte, electric potential, and applied electric current were evaluated in order to determine the effects produced by electroosmosis, diffusion, hydraulic gradient, and electromigration on the removal of vanadium from the catalyst. It was observed that migration is the most relevant phenomenon in the remediation tests, and for the best remediation condition, the migratory flow accounted for about 87 % of the vanadium removal.

石化行业固体废物脱钒运输现象评价

对运输现象进行了研究，该现象涉及电动修复过程，该过程用于从油催化裂化中的失活催化剂中去除钒，该催化裂化目前已分配给水泥厂和I类垃圾填埋场。为了确定电渗，扩散，水力梯度和电迁移对从催化剂中除去钒的影响，对诸如电解质浓度，电势和施加的电流等变量进行了评估。观察到迁移是补救测试中最相关的现象，对于最佳补救条件，迁移流量约占钒去除量的87％。
