System for processing of carbonaceous compositions, has tank agitator configured to agitate graphene oxide in tank after graphene oxide is transferred to tank, where reaction system transfers graphene oxide from reaction vessel to tank.

LAINE S

Apparatus, useful to remove e.g. copper from graphene sheet, includes circulation part in which cleaning solution is directly supplied to catalyst metal of graphene sheet along direction parallel to transferring direction of auxiliary tank.

NA D H

Apparatus of removing catalyst metal on graphene sheet used as transparent electrode film of e.g. flexible display, controls holder to exercise in the state that is completely sunk under catalyst metal cleaning solution.

YOON J H, NA D H

Making graphene powder useful in carbon-based electrical devices involves preparing graphene solution in which graphene particles are dispersed in a solvent; aggregating the particles; separating aggregated particles from solvent and drying.

LEE S, LEE D, SEO B, BYUN N

Preparing graphene oxide that is useful in e.g. transistor, comprises e.g. diluting washed graphite oxide with excess of deionized water and then filtrating using filter, and vacuum drying filtered graphite oxide and heating.

PARK H, KIM S H

Graphene producing device, comprises fixing unit in which graphite catalyst in form of roll is wound in rolled condition with predetermined distance away from locking position, where heating unit heats graphite catalyst during annealing.
