A Theoretical Study of Heterogeneous Methane Reaction Processes
Аннотация
An original mathematical model is developed of the methane pyrolysis process during its filtering through a
porous medium, with taking into account the micro-and macroporosity of the porous skeleton particles. The
calculation results are compared with experimental data. Criteria correlations between dimensionless parameters
are derived, namely, between the degree of metamorphism of the porous skeleton, the structure parameter, and
the dimensionless time, which enable one to treat, within a unified approach, heterogeneous reactions of
different types such as addition (for example, pyrolysis of methane) and decomposition (gasification). The
values of characteristic times of the processes of pyrolysis of methane and gasification of anthracite, calculated
by the suggested criteria correlations, are compared with experimental data.
