Abstract
The dissociation of methane in the nitrogen flowing afterglow of a microwave plasma has been studied. The yields of C 2 hydrocarbons were analysed by gas chromatography and were calculated by numerical simulation. The modelling was based on a macroscopic kinetic approach including a set of 166 reactions and 45 species. A good agreement is obtained between measurements and modelling. Acetylene formation (6–9%) shows a different behaviour compared to the formation of ethane and ethene (0.3–1.1%). By means of the computer modelling, an interesting result was obtained concerning the important role of atomic carbon in the production of acetylene. The main reaction leading to C atom formation is CH 4 +N 2 (a ′)→ C + 2H 2 +N 2 . Then C atoms can react with CH 3 or CH 2 radicals and thus give acetylene.
