▎ 摘　　要

NOVELTY - The reactor comprises a container that is arranged to hold an electrolyte solution. A porous chamber holds a parent material comprising coke, and where the solution is in fluid communication with the parent material. A pressure source positioned to apply a pressure to the chamber to compress the material in the chamber. An electrical power source in electrical communication with first and working electrodes. The porous chamber has pores with pore sizes of 10 nanometers to 10 micrometers. USE - Reactor for electrochemical exfoliation of a petroleum coke feedstock to produce graphene. ADVANTAGE - The reactor enables electrochemical exfoliation of high-quality graphite and other carbonaceous materials with relatively large amounts of sp 2 hybridized carbon to produce good quality exfoliated product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of electrochemical exfoliation. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a method for electrochemical exfoliation. 46Feed 54Sediment parent material 58Mixture 62Recycle 64Exfoliated material
