Methods, devices and systems for processing of carbonaceous compositions

A reaction system comprising:

• a) at least two reaction vessels comprising a carbonaceous composition comprising graphite, each vessel comprising:
• i) a reaction mixer mounted to the vessel, the reaction mixer in fluid communication with the vessel;
• and
• ii) a reaction agitator mechanically coupled to the reaction mixer, wherein the reaction agitator is configured to agitate the carbonaceous composition in the vessel,
• wherein the graphite undergoes an oxidation reaction within the reaction vessels to form graphene oxide;
• and
• b) a tank having a volume of at least a combined volume of the at least two reaction vessels, the tank comprising:
• i) a tank mixer mounted to the tank, the tank mixer in fluid communication with the tank;
• and
• ii) a tank agitator mechanically coupled to the tank mixer, wherein the agitator is configured to agitate the carbonaceous composition in the tank after the carbonaceous composition has been transferred to the tank, wherein the tank is configured to quench the oxidation reaction using at least ice or chilled water;
• c) a micron filter comprising a plurality of layers configured to retain at least 95% w/w of a graphene oxide from a carbonaceous composition while allowing a filtrate comprising waste products, unreacted reaction components, or impurities to drain through the micron filter;
• wherein the reaction system is configured to transfer the carbonaceous composition from the reaction vessel to the tank after the graphite is converted into graphene oxide.
