NOVELTY - Continuous reactor (10) or reactor system comprises: (A) first body (16) having outer wall and second body (12) comprising inner wall (14), where the inner wall defines bore and the first body is configured within the bore and a motor is configured to rotate the first and/or second body at a rate of 300-500 rpm; (B) reaction chamber (15) is configured betwecomposition by aqueous base; composition includes about 2.0% toen the outer wall of the first body and the inner wall of the second body; (C) first inlet and second inlet disposed at or near first end of the reactor and is configured to be in fluid communication with the chamber; (D) first and second outlets disposed downstream from the first and second inlet at or near second end of the reactor, the first and the second outlets are configured to be in fluid communication with the chamber; USE - The system is useful for producing graphene or inorganic 2-dimensional compound. ADVANTAGE - The system: enables dramatically shortened time and significantly reduced amount of chemicals; doesn't requires the use of large quantities of several undesirable chemicals e.g. sulfuric acid, nitric acid and potassium permanganate or sodium chlorate; and doesn't requires long intercalation and oxidation time, typically 5 hours to 5 days. DETAILED DESCRIPTION - Continuous reactor (10) or reactor system comprises: (A) a first body (16) comprising an outer wall and a second body (12) comprising an inner wall (14), where 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 at a rate of 300-500 rpm; (B) a reaction chamber (15) is configured 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 or near a first end of the reactor and being configured to be in fluid communication with the reaction chamber; (D) a first outlet and a second outlet disposed downstream from the first and second inlet at or near a second end of the reactor, trial or an inorganic layered compound dispersed in a liquid medium, through the first inlet into the reaction chamber, driving the reactants downstream towhe first outlet and the second outlet being configured to be in fluid communication with the reaction chamber; and (E) a flow return conduit having a first conduit inlet in fluid communication with the second outlet of the reactor and having a first conduit outlet in fluid communication with the second inlet of the reactor, where the reactor or reactor system is operated to receive a first stock of reactants, containing a graphitic mateard the first and second outlet and facilitating reactions between the reactants to produce a first product slurry, driving the first product slurry through the flow return conduit and the second inlet of the reactor to re-enter the reaction chamber, and further driving the first product slurry downstream toward the first and second outlet to form a second product slurry, which is discharged off the reaction chamber through the first outlet of the reactor or driven to flow through the conduit to return to the reaction chamber through the second inlet for at least another time and the first body has a length and a diameter and the length-to-diameter ratio is no greater than 30. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the new continuous reactor having flow return conduit.
