Three kinds of reactive adsorption desulfurization agents Ni/ZnO-SiO_2-Al_2O_3,NiO/ZnO-SiO_2-Al_2O_3 and NiS/ZnO-SiO_2-AlO_3 are prepared by dry mixed method.The evaluation test for desulfurization of FCC gasoline is carried out in a fixed bed reactor.Desulfurization activity of adsorbents with different Ni chemical speciation is investigated,showing the activity sequence of Ni/ZnO-SiO_2-Al2O3＞NiO/ZnO-SiO_2-Al_2O_3＞NiS/ZnO-SiO_2-Al_2O_3.The optimal operating conditions for FCC gasoline desulfurization of Ni/ZnO-SiO_2-Al_2O_3 are reactive temperature of 370℃,total pressure of 2.0 Mpa,volume space velocity of 5.0 h-1 and H2/oil molar ratio of 2.6.Under the optimum operating condition,the breakthrough curve of reactive adsorption desulfurization is measured,from which the saturation sulfur capacity of adaorbent is obtained.
