NOVELTY - A selective fuel oil desulfurizing adsorbent comprises 1-3 parts mass copper chloride, 3-5 parts mass iron ion, 100-150 parts mass graphene powder, 10-12 parts mass potassium permanganate, and 50-80 parts mass ethanol solution. USE - Selective fuel oil desulfurizing adsorbent. ADVANTAGE - The adsorbent has excellent adsorption-desorption capability, and is economical and environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of adsorbent, which involves adding graphene powder to potassium permanganate solution, stirring, drying at 80-120 degrees C for 3-5 hours, ion-exchanging with iron ion for 1-2 hours, drying, washing with deionized water until the eluate has no iron ions detected, adding ethanol solution and copper chloride, washing, drying, and calcining at 380 degrees C for 3 hours.
