▎ 摘　　要

NOVELTY - Device for preparing graphene using biomass pyrolysis oil, comprises a feeding unit, a preparation unit, a reactor (3), a pressurizing unit, a heating unit and a gas supply unit (19). The feeding unit is placed above the preparation unit for providing biomass pyrolysis oil to be treated. The bottom of the preparation unit is set with the open reactor, a first pressurized column (4), a second pressurized column (7), an orifice plate (8) and a slide. The first pressurizing column is located above the second pressurizing column. The lower surface of the first pressure-increasing column and the upper surface of the second pressure-pressing column are provided with a card slot for placing the metal foil. The biomass pyrolysis oil is set between two metal foils. The orifice plate is placed below the second pressurized column and connected to the slide. USE - The device is useful for preparing graphene using biomass pyrolysis oil (claimed). ADVANTAGE - The device has simple structure and easy operation, achieves high-value utilization of biomass pyrolysis oil, and is economical. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the device for preparing graphene using biomass pyrolysis oil. Reactor (3) First pressurized column (4) Second pressurized column (7) Orifice plate (8) Gas supply unit (19)
