▎ 摘  要

NOVELTY - The removing method of thiophene sulfur involves using silver(I) oxide/silicon dioxide-graphene oxide composite aerogel as an adsorbent, filling the adsorbent into a fixed bed absorption device at 0-100 degrees C, introducing simulated gasoline containing thiophene sulfur at a space velocity of 1-10 h-1, and adsorbing to obtain simulated gasoline with sulfur concentration of less than 10 ppm. USE - Removal of thiophene sulfur from fuel oil. ADVANTAGE - The method enables removal of thiophene sulfur with excellent adsorption property, mild adsorption condition, and low requirements for adsorption equipment, by simple, economical and environmentally-friendly processes.
