Series of works includes 22 scientific works published during 5 years.

New technologies of materials obtaining through hydrocarbon gases pyrolysis in electrothermal fluidized bed were developed.

The raw of fundamental results were obtained, including the following: efficiency of encapsulation with pyrocarbon due to technology of hydrocarbon gases pyrolysis in electrothermal fluidized bed was justified, main indicators of technology and content of waste gases depending on parameters of the process were determined.

Series of scientific works contains high-priority results, like development and construction of high-temperature laboratory and pilot pyrolysis facilities, suitable for research of thermophysical and technological processes in electrothermal fluidized bed.

Among the other new approaches, methodology of calculation of carbon amount, which is extracted by gases in the process of pyrolysis for the cases when it is impossible to measure the amount of high-temperature waste gases was developed and implemented. The innovative method of determination of efficiency of solid phase creation process based on comparison of carbon potentials of initial and final mixtures of gases and graphite was proposed for the first time.

Authors have set new non-traditional challenges, including study of mechanisms and thermodynamic peculiarities of hydrocarbon gases pyrolysis process, research of electrothermal heating of conducting particles of fluidized bed, research and determination of its peculiarities comparing to the traditional methods of heating.

Results of series are of significant importance for nuclear power (obtaining coated particle fuel), solar power (production of semiproduct for obtaining pure silicon, new semiconducting materials and obtaining of silicon carbide), metallurgy (production of charge for carbothermal reduction of thermodynamically stable oxides).

Results of researches were stated in 22 publications, including 14 articles in abstract journals,3 patents. Citation index according to Scopus databases is 1. Works of author were quoted in more than 12 scientific and scientific-applicative journals.
