▎ 摘　　要

NOVELTY - Graphene-based high-efficiency desulfurization adsorbent comprises 30-50 pts. wt. graphene oxide, 10-20 pts. wt. nanozinc oxide, 15-20 pts. wt. aniline, 5-10 pts. wt. ammonium persulfate, 20-30 pts. wt. diluted hydrochloric acid and 60-80 pts. wt. deionized water. USE - Graphene-based high-efficiency desulfurization adsorbent. ADVANTAGE - The adsorbent has high specific surface area, good absorbing effect and desulfurizing effect, high adsorption capacity, simple preparation, and environment-friendly property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene-based high-efficiency desulfurization adsorbent comprising adding graphene oxide to deionized water, and uniformly dispersing to obtain graphene oxide dispersion; mixing aniline, ammonium persulfate and dilute hydrochloric acid to obtain mixed solution; adding mixture in graphene oxide dispersion, stirring uniformly, adding nanozinc oxide, and performing hydrothermal reaction for 30-60 minutes; and centrifuging, filtering, and drying precipitates.
