摘要
采用强磁场磁选技术 ,可以有选择地、大量地从催化裂化平衡剂中剔除老化程度高、受重金属 (Ni、V、Fe)污染程度深的催化剂颗粒 ,使催化剂平衡活性得到改善 ,在减少新鲜催化剂补充量的基础上 ,提高原料油的总体转化水平。着重考察了华北、燕山等 6家炼油企业催化裂化平衡催化剂经强磁场磁选后 ,回收部分的产率与磁化率的关系 ,以及采用最佳磁化率下的低磁剂样品与其原始平衡剂和高磁剂的重金属含量、微反活性的对比关系 ,提出了强磁场磁选技术在催化裂化工艺中的应用模式。
Highly aged and heavy metal contaminated catalysts can be sorted out and removed from FCC equilibrium catalyst with strong magnetic separation technology to improve the equilibrium catalyst activity. The transfer ratio of feed oil will increase with the decrease of supplement of fresh catalysts as well. The application model of strong magnetic separation technology in FCC process is proposed based on the relationship between the magnetic susceptibility and the recovery rate of FCC equilibrium catalyst. The comparison of the content of heavy metal and micro-activity of low magnetized catalyst, the original equilibrium catalyst and high magnetized catalyst are also reported.
