Processes in CH4/N-2 microwave plasma are studied by computer experime
nt based on experimental data derived from the nitrogen flowing afterg
low discharge, By means of a macroscopic kinetic approach, the origina
l model consisting of 61 chemical reactions between 24 active species
in the discharge is analysed in detail, the main attention being devot
ed both to the initial stages of methane decomposition and to the yiel
d of stable products together with the most important reactions for th
e production of individual species. From these reactions the new simpl
ified model is formulated. (C) 1998 Elsevier Science Ltd. All rights r
