The results show that nickel on the spent FCC catalyst can be removed significantly, and the maximum nickel removal is up to 80%. Meanwhile, compared with the spent FCC catalyst, the nickel-removed catalyst exhibits excellent stability.

• 实验结果表明,该技术对脱除废流化催化裂化催化剂上的镍效果显著,脱镍率最高可达80%25,脱镍后的催化剂微反活性大幅度提高,并且稳定性较好。
