| 摘 要： | Elements including P, Sb, Ce, La, B, Sn, Ti, Bi and Mg that could passivate Ni and V were studied on their migration on FCC catalysts and carriers under simulated commercial FCC operating conditions. Test results had shown that P, Sb, B and Sn compounds exhibited migration activity. The effects of temperature, fluidizing medium and contact time on migration of antimony compounds were investigated, and the mechanism regarding antimony migration was proposed. Meanwhile, it Was disclosed that Ni on catalyst could stimulate Sb contained in the metal passivator to move onto FCC catalyst in tandem with the interaction between nickel and antimony.
