PL-4HIGH TEMPERATURE PROCESSES OF NANOSTRUCTURALCARBON MATERIALS PRODUCTIONLikholobov V.Institute of Hydrocarbons Processing,Omsk Scientific Center SB RAS, Omsk, RussiaThe past decades were marked by impressive achievements in studying theproperties of earlier discovered various forms of nanostructural carbon such asfullerenes, nano-onions, nanotubes, nanoglobules, nanofilaments, nanofibrils,graphenes, and others. The obtained results demonstrate that the totality of physicaland chemical properties of these materials makes them basic for solving theproblems of future nanoindustry. However, technologies underlying the production ofsuch materials in practically significant amounts (kilograms, tonnes) are not faradvanced, which is a hindering factor. Irrespective of a recent breakthrough (thetonnage production of C 60 /C 70 fullerenes and multiwalled carbon nanotubes),production of nanostructural carbon materials remains quite a topical problem.Most of the above-listed nanostructural carbon materials are obtained via hightemperature decomposition of various hydrocarbons in the gas phase (with solidcarbon forming in the gas phase) or in the presence of solids acting as matrixcatalysts (with carbon phase growing on a matrix). So, special reactor units areneeded for the development of appropriate technological processes.The lecture considers the production of nanostructural carbon materials fromgaseous and liquid hydrocarbon feedstock via the step of carbon nanoglobulesgeneration. Data on the nature of corresponding molecular precursors, factorsdetermining the rate of carbon phase formation, regularities of its growth intonanoglobules and their agglomeration into secondary structures are analyzed.Advanced physical methods, including the high resolution electron microscopy, wereused to study the specific structure of primary and secondary particles on micro- andnanoscales.Operation parameters of the reactor unit producing nanoglobular carbon of aspecified structure were determined.14
