Adsorption desulfurization performance and mechanism over nanocrystalline NiO/Al2O3-1 adsorbent

Resumo

Desulfurization performance was evaluated by an adsorption model or real oil (diesel and kerosene) at low temperature using nanocrystalline NiO/Al₂O₃-1 adsorbent in static equipment. The properties of the NiO/Al₂O₃ adsorbent samples were characterized by BET surface areas, transmission electron microscopy, FTIR spectra, and TG-DTG curves. Desulfurization experimental results indicated that the desulfurization efficiency for kerosene is much higher than that for diesel due to the π-electronic interaction and S–M bonds with NiO/Al₂O₃-1 adsorbent. Also, a performance of adsorbent regeneration was kept well for multiple cycles.
