Carbon nanomaterials (CNMs) – carbon nanofibres (CNFs) and nanotubes (CNTs) have a
lot of unique features of great interest for scientists and engineers all over the world. These
materials are filament carbon structures with diameter from 1 to hundreds nanometers and
with length up to several micrometers. Perfect strength in combination with elastic
deformation high values, good electrical conduction and autoelectronic emission ability are
typical for CNMs. They can be catalyst carrier, sorbents, supercondenser components and
composite materials, additives which improve operating properties of lubricants, ceramics etc.
But the wide use of CNMs is restrained because of their high cost which is connected
with the power consumption and complexity of the equipment on using arc and laser thermal
methods for the production of these materials.
Tambov Innovative Technological Center for Mechanical Engineering had been carried
out research and construction works on the development of CNF technologies and equipment
for its industrial-scale production.
The scientists of several institutes of the Russian Academy of Sciences, particularly Ioffe
Physical and Engineering Institute, Solid State Physics Institute and High-Molecular
Compounds Institute, Voronezh State Technical University, Company “Nanoindustry” and
also firms and research institutes in our region were our partners.
As a result of the analysis of the existing methods and techniques for carbon
nanostructure obtaining we made a conclusion that catalytic pyrolysis of carbon gases is the
most perspective way to produce CNFs in industrial amounts and with low production costs.
First they are methane and butane-propane mixtures of the certain ratio.
It is known that in the USA, Japan, China and in some countries of Western Europe
CNMs production is organized in industrial amounts but any information about the equipment
used is absent in the mass media by clear reasons.
On the first stage of the project realization we carried out complex lab research in carbon
gas pyrolysis in different reactors, including those with catalytic vibrofluidized layer where
