In the paper a number of fundamental and applied results were obtained, among which the efficiency of the technology of pyrocapsulation was proved precisely by the technology of hydrocarbon pyrolysis in an electrothermal fluidized bed (ETFB), and the composition of the waste gases was determined depending on the process parameters.  The possibility of thermal purification of natural graphite in an electrothermal fluidized bed was proved theoretically and experimentally. The research results allow to create energy- experimentally efficient and ecological technology for purification of natural graphite.

Among the new approach a calculating method of the carbon amount released by gases in the pyrolysis process is developed and implemented for cases where it is impossible to measure the amount of high-temperature waste gases. For the first time, it was proposed a method which permits to determine the efficiency of the solid phase formation process, which is based on the comparison of thermodynamic carbon potentials of the initial and final mixtures of gases and graphite.

The results of this cycle of scientific works may be employed in nuclear power engineering (obtaining coated particle fuel, silicon carbide production), hydrogen energy (hydrogen production), electric transport (graphite cleaning), solar power engineering and electrical engineering (high-purity silicon production), special metallurgy (production of a charge for the carbon-thermal restoration of thermodynamically stable oxides) and the energy of ecology.
