RESEARCH OF THE TECHNOLOGY OF CARBON NANOTUBES PRODUCTION IN GAS MIXTURES CONTAINED CARBON MONOXIDE

Abstract

Analysis of existing methods of carbon nanotubes (CNTs) obtaining shows the advantages of the method of catalytic synthesis. This method is differed by relatively low energy consumption, use of cheap raw materials, an ability to create high-performance industrial production, relative simplicity of equipment and also by the lack of thorough cleaning of the resulting product. Catalytic synthesis methods differ one from another by use of raw carbon material type, catalyst type on which carbon is deposited and temperature regimes. As the basic technology it was used process at moderate temperatures (in the range of a netic-thermodynamic maximum of passing of Bell-Boudoir reaction). Products of air conversion of natural gas with strictly controllable hydrogen, carbon and oxygen potentials were used in a role of reactionary gas. Also, a possibility of CNTs manufacturing from a producer gas was explored. Maximum output of a final product has been achieved on an iron-ore concentrate of the Inguletsky ore mining and processing enterprise (Krivoi Rog) which used among many in the capacity of the catalyst of CNTs formation.
