METHOD OF TREATMENT OF GRAPHITE AND THE REACTOR FOR ITS REALIZATION Russian patent published in 2007 - IPC C01B31/04 C25B1/00 

FIELD: atomic industry; chemical industry; metallurgy; heat power engineering; methods and reactors for graphite treatment.

SUBSTANCE: the invention is pertaining to the field of the atomic industry, chemical industry, metallurgy and heat power engineering and may be used for production the flexible graphite foil, sorbents, catalytic agents, chemical sources of electric current. Suspension of the graphite in the electrolyte, for example, in the nitric acid having the electronic conduction from the hopper (15) through the branch pipe (8) load into the reaction chamber formed by the cathode (3) and the consumed anode (7) from the anode-soluble in the electrolyte metal or its alloy. The anode (7) is arranged in the lower part of the body of the reactor(1) and is made in the form of the movable band, which ends are consolidated on the unwinding drum (10) and the winding drum (11). On the exterior side of the cathode (3) the diaphragm (5) is disposed. Conduct an anodic oxidation of the graphite with production of the compounds of the anodic oxidation containing the compounds of embedding in the graphite (CEG) and the cations of the metal of the anode (7) at the suspension movement through the reaction chamber. The products of the anodic oxidation are cleared off from the surface of the cathode (3) by the fluoroplastic knife (16) and through the branch pipe (9) unload it into the hopper-collector (17). Then they are subjected to the hydrolysis or they are added with the alkali or the soda ash, flushed and dried with production of the oxidized graphite with the hydroxides of metal or without them. After that they conduct the thermal expansion. The invention allows to make the technological process cheaper and to dilate the production capabilities due to production both of the conventional foam graphite and the composite material based on the foam graphite with addition of the metals or their oxides.

EFFECT: the invention allows to make the technological process cheaper, to dilate the production of the conventional foam graphite and the composite material based on the foam graphite with addition of the metals or their oxides.
