▎ 摘 要
NOVELTY - The method involves injecting coal tar from a nozzle of a venturi ejector. The coal tar and an oxygen-argon gas mixture are added that contains nano-catalyst to the venturi extractor together from an air suction pipe at the diffusion pipe. The magnetic auxiliary electric arc plasma generating device is entered, and generated coal tar by high-temperature catalytic pyrolysis reaction under the action of nano catalyst and high-density electric plasma. USE - Method for continuous preparation of graphene by one-stage pyrolysis of coal tar in producing graphitize carbon by using large number of polycyclic aromatic hydrocarbon. ADVANTAGE - The method ensures dangerous waste coal tar as carbon source, resource utilization and environment-friendly, by electric arc plasma discharge can realize high quality, high yield of the graphite of the alkene, simple method, can be continuously produced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device for continuous preparation of graphene by one-stage pyrolysis of coal tar. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a method for one-stage pyrolysis coal tar continuous preparation graphite.
