摘要：The effect of nitrogen compounds in FCC gasoline on reactive adsorption desulfurization (RADS)was investigated over NiO/ZnO-Al2O3-SiO2 adsorbents. On the basis of ammonia temperature-programmed desorption (TPD), pyridine infrared radiation (Py-IR), and X-ray diffraction (XRD), adsorbents calcinated at 500 degrees C exhibit weak acidity and strong acidity, high Br delta nsted acidity, and good dispersion of the active components. High Br delta nsted acidity adsorbent presents the best RADS ability, contributing to adsorption and removal of nitrogen compounds. The results show that the basic nitrogen quinoline and pyridine inhibit significantly RADS, but the nonbasic nitrogen carbazole only affects RADS mildly. The order of inhibition is quinoline > pyridine > carbazole.
