A device for preparing graphene from biomass pyrolysis oil

Abstract

The invention belongs to the field of biomass utilization and specifically discloses a device for preparing graphene by using biomass pyrolytic oil. A feed unit is arranged above a preparation unit; the preparation unit is arranged in a reactor open at the bottom; a first pressure column is positioned above a second pressure column; a clamp slot is formed in the lower surface of the first pressure column and the upper surface of the second pressure column respectively, to place metal foil; a pore plate is arranged below the second pressure column and is connected with a slide way; the pore plate and the second pressure column are driven by the slide way to move up and down, so as to replace the metal foil conveniently; the pressure unit is used for driving the first pressure column to move up and down and exert pressure on the first pressure column; a heating unit is used for heating the first pressure column and the second pressure column to the preset temperature; a gas supply unit is connected with the reactor. The device disclosed by the invention has a simple structure and is easy to operate; moreover, high-value utilization of the biomass pyrolytic oil can be realized, and the production cost of graphene can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of biomass utilization, and more specifically relates to a device for preparing graphene by utilizing biomass pyrolysis oil. Background technique [0002] Biomass is clean, renewable, widely distributed and carbon neutral. The development of biomass utilization technology is conducive to optimizing my country's energy supply structure and alleviating increasingly severe environmental problems. Biomass has the characteristics of dispersed raw materials, small collection radius, and high transportation and storage costs. Converting biomass into biomass pyrolysis oil can make its energy density 5 to 10 times that of raw materials, which is convenient for transportation and storage. [0003] Biomass pyrolysis oil has a wide range of uses. For example, biomass pyrolysis oil can be directly burned in a boiler for heating or power generation; it can also be gasified by a gasifier or steam reformed to produce syngas or hydro...
