METHOD AND THE INSTALLATION FOR PRODUCTION OF THE THERMOEXTENDED GRAPHITE Russian patent published in 2007 - IPC C01B31/04 

FIELD: chemical industry; other industries; methods and devices for production of the thermo-extended graphite.

SUBSTANCE: the invention may be used at manufacture of the flexible articles, composites, gaskets, compactions, coatings, antifriction and thermal-protective materials, sorbents. The heating chamber (4), the bottom of which is made in the form of the inverted cone, is charged with the oxidizing catalyst from the hopper (1) having the batcher (2) and the branch-pipe (3). Then fill the hopper (1) with the oxidized graphite and switch on the heating components (5). After reaching the temperature of 600-800°C they switch off the heating. Feed the working oxygen-containing gas through the branch-pipe (10), the gas-carrier - the fuel gas feed through the branch-pipe (3), at their volumetric ratio equal to the stoichiometric value so ensuring the fluidization of the catalytic agent. The oxidized graphite from the hopper (1) is fed into the chamber (4) and passes through the fluidized layer of the catalytic agent. Then it is fed into the chamber of rarefaction (8), the lower part of which is made in the form of the funnel out of the porous gas-permeable material at the simultaneous chilling by the stream of the gas-thinner fed through the nozzle (6). The refrigerated expanded graphite is fed in the collector (7). The invention allows to intensify the process and to increase the efficiency of the installation.

EFFECT: the invention ensures the production process intensification and the increased efficiency of the installation.
