A cyclonic separator is taught for separation of a mixed liquid phase/gas phase process stream. The cyclonic separator comprises an outer shell, at least two cyclonic chambers located within the outer shell, each cyclonic chamber having an upper end and a lower end; a single, common tangential inlet passing tangentially through the outer shell and into each of the at least two cyclonic chambers, proximal the upper ends thereof; a gas outlet tube located at least partially within each cyclonic chamber, extending axially from a lower gas outlet end located below the tangential inlet, to an upper gas outlet end extending out of each of the at least two cyclonic chambers, said upper gas outlet ends being in fluid communication with a common gas chamber located above the outer shell; and a circumferential recycle opening formed around and through a thickness each gas outlet tube, in a portion of each gas outlet tube located axially between the upper end of cyclonic chambers and the common gas chamber, said recycle opening thus being in fluid communication with an inside cavity of the outer shell.

The disclosure provides a system and method for production of activated carbon from a coal-originating particulate feed material. Feed material and activating gas are introduced into a reaction chamber, the activating gas being introduced at a velocity above the average terminal velocity of particles within the feed material. Feed material is then entrained in the activating gas such that a recirculating flow path for the feed material is established within the reaction chamber. Activated material may then be recovered from the chamber.
