摘要：
Plasma processing of CH4+CO2 mixture can lead to the formation of synthesis gas (CO+H-2). The use of cold plasma for this type of process seems very promissing. We report here the determination of vibrational and rotational temperature in several gases (CH4, CH4+CO2) at atmospheric pressure. The plasma is created by high voltage (90 kV), fast pulse (20 ns) Dielectric Barrier Discharge in tubular cell. The measured average rotational temperature is very low T-rot approximate to 650 K; on the other hand the vibrational temperature is high T-vib approximate to 5500 K and may explain the good chemical plasma reactivity.
