| Abstract: | A new gas activation method was proposed to remove nickel from spent fluid catalytic cracking (FCC) catalyst effectively. The effects of gas-activation conditions and acid cleaning condition on nickel removal and activity rejuvenation, the stability of the nickel-removed catalyst were investigated. 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. |
