Abstract
Plasma processing of a (CH 4 +CO 2 ) mixture can lead to the formation of synthesis gas (CO+H 2 ). The use of a nonthermal plasma for this type of process seems very promising. We report here an electric and spectroscopic characteristic of plasma created in a (CH 4 +CO 2 ) mixture by a high-voltage, steep front-voltage (>10 12 V/s), very-short-pulse triggered dielectric barrier discharge in a tubular cell. Particular attention was payed to the determination of the rotational temperature for C 2 . Time resolved investigation of the Swan band leads to an estimated value around 3000 K.
