▎ 摘　　要

NOVELTY - Preparing graphene using biomass pyrolysis oil comprises (a) mixing biomass pyrolysis oil to be treated with organic matter to obtain mixed liquid, and placing mixed liquid on metal foil, (b) mechanically pressurizing metal foil to which mixed liquid is attached under the condition of insulating air, heating to 300-400 degrees C for a preset time, then heating to 800-1200 degrees C for a preset time, and performing pyrolysis reaction of biomass pyrolysis oil to be treated to form graphene, and (c) completing pyrolysis reaction, and separating the obtained graphene from the surface of metal foil to obtain required graphene. USE - The method is useful for preparing graphene using biomass pyrolysis oil. ADVANTAGE - The method: utilizes biomass pyrolysis oil which is easy to deposit carbon and coke; and realizes the high value utilization of biomass pyrolysis oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene prepared by the above mentioned method.
