Particulate sorbent with substantially reduced valence promoter metal nickel supported on Zinc Titanate or Zinc Ferrite provides a system for the desulfurization of a feed stream of FCC gasoline.The optimum preparation conditions for this sorbent were that the concentration of nickel nitrate was 10 mol/L,dipping time 1 h,baking temperature 600℃,and baking time 1 h.The sorbent exhibited an excellent desulfurization capacity in a fixed-bed absorber at 350℃ and 0.75 MPa.Sulfur content in FCC gasoline was reduced to 50 μg/g;the lifetime of the regenerated sorbent was 150 h;the octane number was about 89 when the ratio of H₂/gasoline was optimum;the yield of gasoline was about 98%;the amount of end hydrogen (400 mL/min) can influence the effect of desulfurization.
