▎ 摘　　要

NOVELTY - The preparation method of pore-rich thin layer graphene, involves pre-treating the oil raw material using catalytic oil slurry or residual oil through delayed coking treatment to obtain the coking liquid product as pre-processing raw material oil. The oil is raw material and cut. The solvent is extracted to obtain the distillate oil aromatic hydrocarbon extracting oil. The reactants are processed by extracting oil from fraction oil aromatic hydrocarbon and organic solvent, adding template agent to disperse, evaporating the organic solvent solid-liquid mixture to obtain the template agent powder of surface-coated distillate oil aromatic extracting oil. The rich-hole graphene layer-like material is prepared by calcining the template agent powder, the calcined product is washed by acid washing to remove template agent. Hole-rich thin layer material graphene is obtained. USE - Preparation method of pore-rich thin layer graphene used in super capacitor, petrochemical industry and carbon nano material. ADVANTAGE - The method is simple, the raw material source is wide, the application prospect is good and it is easy for industrial production. The graphene material has high uniformity degree, thin layer, and presenting shell shape, especially for catalytic oil slurry and rich in thick ring aromatic hydrocarbon of high added value utilization. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope graph of the porous thin layer curved type graphene.
