Objective of the work is to study thermochemical processes in an electrothermal fluidized bed (the preparation of pyrolyzed carbon-encapsulated materials by the pyrolysis of hydrocarbon gases and the purification of natural graphite).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 thermochemical 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.

The possibility of thermal purification of natural graphite in an electrothermal fluidized bed has been theoretically and experimentally tested. The results of the research make it possible to create an energy-efficient and ecologically clean technology for the purification of natural graphite to higher purity levels (nuclear purity).Results of series are of significant importance for nuclear power (obtaining coated particle fuel), solar power, metallurgy (production of charge for carbothermal reduction of thermodynamically stable oxides).
