▎ 摘  要

NOVELTY - Removal of thiophenic sulfur in gasoline involves filling silver oxide/silica-alumina-graphene oxide composite aerogel as adsorbent into a fixed-bed adsorption device, and introducing simulated gasoline containing thiophenic sulfur at 1-10 hour-1 and 0-100 degrees C, such that sulfur concentration in the of gasoline after adsorption is 10 ppm or less. USE - Removal of thiophenic or benzothiophenic sulfur in gasoline. ADVANTAGE - The method enables efficient removal of thiophenic or benzothiophenic sulfur in gasoline under mild adsorption condition with low requirement of adsorption equipment. The adsorbent can be prepared by simple and economical process, and is environmentally-friendly, and can be repeatedly used.
