FULLERENE PRODUCTION PLANT Russian patent published in 2003 - IPC

FIELD: carbon materials. SUBSTANCE: in working chamber receiving neutral gas, discharge distance between graphite materials is fixed. Graphite materials' processing flow is affected by electron stream from emitter 18, acoustic emission from emitter 19, infrared emission from emitter 21, and ionized infrared emission from emitter 22. Slag is withdrawn over reverse-oriented cavities 20. Selective classification of fullerenes is effected on electrostatic separators 24, 25, and 26, wherein fullerenes C₆₀, C₇₀, C₈₄, respectively, are accumulated. Processing flow can also be affected by electromagnetic emission from additional emitter 23. Accumulated fullerenes are driven off to be directly employed in chemical industry or to be stored. Gas from connecting pipe 17 is transferred on filters 18 and then returned to chamber 1 through connecting pipes 12 and 13. EFFECT: increased productivity pf plant, enhanced efficiency of separating fullerenes from slag and in classification of fullerenes, improved control of parameters and composition of produced flow. 2 cl, 2 dwg
