1. A process for manufacturing a graphenic compound, the process comprising:
a. injecting a first stock into a first inlet of a continuous or semi-continuous reactor, the first stock comprising graphite;
b. optionally injecting a second stock into a second inlet of the continuous reactor or semi-continuous reactor, the second stock comprising potassium permanganate;
c. optionally injecting a third stock into a third inlet of the continuous or semi-continuous reactor, the third stock comprising an oxidizing or quenching agent and being injected downstream from the injection point of the first and/or second stock(s);
d. optionally injecting a fourth stock into a fourth inlet of the continuous reactor or semi-continuous reactor, the fourth stock comprising water and being injected downstream from the injection point of the first, second, and third stocks; and
e. collecting the graphenic compound from an outlet of the continuous reactor or semi-continuous reactor, the graphenic compound being collected downstream from the injection points of the first, second, third, and fourth stocks,
wherein the continuous reactor or semi-continuous reactor comprises a reactor chamber into which the first, second, third, and fourth stocks are injected; the reactor chamber being configured between an outer wall of a first cylindrical body and the inner wall of a second cylindrical body or bore, one or both of the first and/or second cylindrical bodies rotating around the axis thereof; and the first and second cylindrical bodies are rotating in opposite directions.
