METHOD OF SWELLING INTERCALATED GRAPHITE Russian patent published in 1999 - IPC

FIELD: environmental pollution removal. SUBSTANCE: material can be used for cleaning various areas from contaminating substances, for example, oil substances by the aid of in situ prepared sorbent. To increase its performance and productivity and to rise its coefficient of efficiency to 96% and to assure highest possible environmental purity of the process itself and ambient medium when applying known method based on external energy- mediated cleavage of intercalated graphite crystalline lattice, the latter, according to invention, is affected by 260 V electric field energy in continuously mode using electrodes, one of them being placed on the base surface of Lavale nozzle, into which intercalated graphite is fed with rate 0.1-0.5 kg/s and wherein the other electrode is placed. EFFECT: enhanced area cleaning efficiency. 2 cl, 1 dwg
