“…Investigations on synthesis of graphene layers in hydrocarbon flame at low pressure have shown that the formation of graphene layers is occurred in sooting zone as well as at atmospheric pressure, as was shown in [22][23][24]. Figure 3 shows the Raman spectra (a) that characterizing the carbon structures are formed on nickel plate in areas 0, 1, 2, 3 (b).…”

Soot formation processes have been studied for more than 100 years, they include empirical and phenomenological description of conversion of various fuels to soot particles. This article provides an overview of current state of soot formation foundations, including the chemistry of soot nucleation, nucleation, mass growth as well as size of soot particles. Consideration of this issue shows that a great progress has been made, but there is still a lot of ambiguity in many areas of our knowledge. This concerns the role of aromatic molecules and radicals in nucleation and subsequent growth mass in laminar pre-mixed flames. Along with environmental problems, in recent time there are considered soot particles as an environment for nanomaterial synthesis, such as fullerenes, carbon nanotubes and graphenes. In this regard, a complete scheme of nanomaterials formation in mode of soot formation has been developed.

“…The nanobeads are morphologically similar to the carbon nanopearls synthesized by Levesque and coworkers [43] by acetylene dissociation at 700 ºC on nickel catalyst nanoclusters. Puri et al [44] have determined new ways of synthesis of carbon nanotubes in the fuel-rich diffusion flames, exposed to an electric field during 2-10 min, on superhydrophobic surfaces representing nanodimensional round amorphous carbon particles deposited on a silicon substrate [45].…”

The seventieth anniversary of Professor Jürgen Warnatz is an important event for the scientific community of investigators of chemical kinetics and computation of combustion. His brilliant research in the field of combustion, particularly in the chemical kinetics reactions should be noted. His manuscript «Combustion» with co-authors is a handbook for specialists in the field of combustion and under my supervision was translated to Kazakh. Professor J.Warnatz contributed much to the development of combustion processes modeling and education of scientists from various countries, including Kazakhstan. The general scheme of conversion of hydrocarbon fuels with new experimental data on the formation of fullerenes and graphenes, taking into account the pressure effect is proposed for the fuel-rich flames. It is shown that the formation of fullerenes is important to the corresponding spatial orientation of PAH, possible at low pressures. The formation of hydrophobic soot surface on silicon and nickel substrates during combustion of propane-oxygen flame was studied. It is stated that the hydrophobic properties are due to the presence of soot particles in the form of nanobeads.

The paper presents the results of carbon nanotubes synthesis from benzene in fluidised bed reactor. Al2O3 spheres with iron and nickel nanoparticles coating were used as a catalyst for the synthesis of carbon nanotubes. To deposit nickel nanoparticles on the surface of Al2O3 spheres, the method of solution combustion was used. Optimum temperature conditions and gas flow rates were worked out for each of the catalysts. It was found that the best efficiency in the synthesis of carbon nanotubes from benzene is shown by catalysts based on aluminium oxide coated with iron. The obtained carbon nanotubes were studied by scanning electron microscopy and Raman spectroscopy. It was found that at temperatures above 850 °C from benzene on Al2O3 spheres with Ni/NiO, carbon frame structures are formed.
