Investigation of Synthesis‐Gas Production via CH4O2Ar Gas Mixture Using Microwave Plasma Torch

“…Recently, non-equilibrium plasma are being used to convert CH 4 into useful products such as higher hydrocarbons, syngas, and organic oxygenate liquid products. [5] The non-catalytic conversion of CH 4 or CH 4 ÀO 2 has been carried out by discharge approaches such as high pulse frequency, [6] corona, [7] radiofrequency (RF), [8] MW, [9] and dielectric barrier discharges (DBDs).…”

“…while noble gas like Ar help the ionization of working gas. [4] In addition, O 2 or CO 2 gas is the source of atomic oxygen. The plasma CH 4 conversion is very effective since various kinds of chemical reactions could be induced through the high energy of the plasma medium.…”

“…[4] In addition, O 2 or CO 2 gas is the source of atomic oxygen. The plasma CH 4 conversion is very effective since various kinds of chemical reactions could be induced through the high energy of the plasma medium. The plasma method also overcomes the drawback of the high temperature required in conventional catalytic processes.…”

“…To analyze the produced gas, the gas chromatography (GC) and the Fourier transform infrared (FTIR) spectroscopy have been used. In order to optimize the production conditions, the effect of O 2 /CH 4 gas flow rate and plasma power in the plasma chemistry phenomenon, CH 4 conversion and CO selectivity have been investigated. Our experimental results confirm our simulations and they are in good agreement with existing literature data so far.…”

[10] These plasmas primarily yielded C 2 hydrocarbons, methanol, or diamond-like carbon film and not extensively syngas.…”
