Abstract

Mathematical models of methane decomposition during its pyrolysis, including nonstationary diffusion equations with and without taking into account the convective component of the decomposition process, have been developed and verified. Their exact analytical solutions have been obtained and further used in the study of a mathematical model of the formation of solid carbon particles arising during methane heating to the pyrolysis temperature. By studying the rate and intensity of the formation of solid carbon particles, it has been shown that particles of the smallest size are obtained at higher decomposition temperatures and for a shorter time.
