▎ 摘　　要

NOVELTY - Graphene adsorbent comprises 10-20 pts. wt. graphene, 20-30 pts. wt. activated carbon, 20-45 pts. wt. potassium permanganate solution, 0.5-1 pts. wt. ammonia water, and 9-16 pts. wt. zinc oxide. USE - The graphene adsorbent is useful for gasoline desufhurization (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for Preparing Graphene adsorbent comprising (i) oxidizing graphene and activated carbon by potassium permanganate solution to obtain graphene oxide and oxidized activated carbon, (ii) mixing graphene oxide and oxidizing activated carbon prepared in step (i) in ratio of 2:3, and (iii) adding zinc oxide and ammonia water to mixture in step (ii), stirring, and hydrothermally reacting at 190-210 degrees C for 20-60 minutes, washing and drying.
