C2H2 production from hydrocarbons process

Translational temperature To in the non-equilibrium plasma system was not sufficient for effective methane conversion, whereas vibrational temperature was able to stimulate the process. The conversion degree of methane into acetylene achieved in the plasma system is presented in Fig. 9-5 as a function of the specific energy input at three different pressures 10, 40, and 80 Torr. When the pressure increases from 10 to 80 Torr, the methane-to-acetylene conversion degree rises and reaches a maximum of 80% at = 2.6 eV/mol CH4. The gas-product composition in this regime is H2,73 vol % CH4,5 vol % and C2H2,22 vol %. The concentration of ethylene, ethane, and higher hydrocarbons is less than 1% soot production...
