催化裂化废催化剂磁分离装置及工业应用

摘要

A magnetic separation process and its separation effect for spentFCC catalyst was introduced.After treating,micro-activity of the catalyst enhanced by 3.8 units,specific surface increased by 30.5%,pore volume increased by 33.3% and wear index decreased by 21.4% respectively.Commercial application showed that make-up of fresh catalyst reduces by 23%.%介绍了催化裂化废催化剂磁分离装置的工艺流程及分离效果。处理后的催化剂微反活性提高3.8个单位，比表面积提高30.5%，孔体积提高33.3%，磨损指数减少21.4%/h。工业应用表明可减少新鲜催化剂用量23%，有较好的经济效益和社会效益。
