Аннотация:A mathematical model was developed for the plasma-chemical pyrolysis of methane, which includes the latest data on the mechanism and kinetics of chemical processes of hydrocarbon pyrolysis and mixing of methane jets with hydrogen heated in an arc plasma torch. The results of calculations on methane conversion and the synthesis of acetylene and its homologues satisfactorily agree with experimental data over a wide range of parameters of the process. It was shown that the methane conversion is initiated via interaction with atomic hydrogen, acetylene is produced through the dissociation of intermediate products involving radicals, and the consumption of acetylene is due to the synthesis of its homologues involving vinylidenecarbene and methylenecarbene in the ground and excited states.
