Simulation of prebiotic atmospheres by atmospheric pressure glow discharge generated in nitrogen-methane gas mixture

Popis výsledku v původním jazyce

We studied chemical reactions in N2 + CH4 mixture initiated by DC glow discharge. This experiment was designed to mimic prebiotic atmospheres. The content of CH4 was set to 2%, the total pressure was set to 101 kPa and the gas temperature to 300 K. The composition of products from these reactions was studied by GC-MS and FTIR. A kinetic model for reactions in this mixture was developed. The influence of CO2 admixture to N2 + CH4 was also investigated experimentally and theoretically. It was assumed that 2% of nitrogen was dissociated to nitrogen atoms in the ground state, the CH4 was fully dissociated into 90% of CH3 and 10% of CH2. This was taken as initial conditions for the calculations and the kinetic equations were solved numerically for time from 0 to 10 s.
