Reactive adsorption of sulfur compounds from FCC gasoline on NiO/γ-Al2O3

摘要：

NiO/γ-Al2O3 adsorbent was prepared by wet impregnated method. XRD, SEM-EDS, nitrogen adsorption techniques were used to characterize the adsorbents and GC-FPD was utilized to analyze the composition of gasoline before and after reaction. X-ray diffraction patterns indicate that noncrystal NiO particles are supported on the surface of γ-Al2O3. The results show that NiO/γ-Al2O3 adsorbent could be used to remove sulfur compounds and is effective on removing benzothiophene (BT). The maximum desulfurization efficiency appears when NiO content reaches 16％, and the total sulfur adsorption capacity is 1.84mg/g, however for 16％Ni/γ-Al2O3 the value reaches 3.495mg/g.
