  • Patent number: 11027252
    Abstract: Provided is a continuous reactor system for producing graphene or an inorganic 2-D compound, the reactor comprising: (a) a first body comprising an outer wall and a second body comprising an inner wall, wherein the inner wall defines a bore and the first body is configured within the bore and a motor is configured to rotate the first and/or second body; (b) a reaction chamber between the outer wall of the first body and the inner wall of the second body; (c) a first inlet and a second inlet disposed at first end of the reactor and in fluid communication with the reaction chamber; (d) a first outlet and a second outlet disposed downstream from the first inlet, the outlets being in fluid communication with the reaction chamber; and (e) a flow return conduit having two inlets/outlets in fluid communication with two ends of the reactor.

  • Publication number: 20210114880
    Abstract: Provided is a process for manufacturing a graphene material, the process comprising (a) injecting a rust stock into a first end of a continuous reactor having a toroidal vortex flow, wherein the first stock comprises graphite and a non-oxidizing liquid (or, alternatively, graphite, an acid, and an optional oxidizer) and the continuous flow reactor is configured to produce the toroidal vortex flow, enabling the formation of a reaction product suspension or slurry at the second end, downstream from the first end, of the continuous reactor; and (b) introducing the reaction product suspension/slurry from the second end back to enter the continuous reactor at or near the first end, allowing the reaction product suspension/slurry to form a toroidal vortex flow and move down to or near the second end to produce a graphene suspension or graphene oxide slurry. The process may further comprise repeating step (b) for at least one time.

  • Patent number: 10953380
    Abstract: Provided is a process for manufacturing 2D inorganic compound platelets, the process comprising (a) preparing a first stock containing a 3D layered inorganic compound material dispersed in a liquid medium, (h) injecting the first stock into a continuous reactor having a vortex flow, (c) operating the continuous reactor to form a reaction product suspension containing 2D inorganic compound platelets dispersed in the liquid medium, and (d) separating and recovering said 2D inorganic compound platelets from said product suspension. The product suspension may be directed to flow back to the continuous director for further processing for at least another pass through the reactor, prior to step (d). The continuous reactor is preferably a Couette-Taylor reactor.
