Plasma chemical reactions of hydrocarbons in an atmospheric pressure dielectric barrier discharge — •Thejaswini H.C., Abhijit Majumdar, and Rainer Hippler — Institut für Physik, Universität Greifswald, Felix-Hausdorff-Str. 6, 17487 Greifswald

The plasma chemical reactions of C₂H₄/N₂, C₂H₆/N₂, C₂H₄/Ar and C₂H₆/Ar have been investigated through mass spectroscopy in a laboratory dielectric barrier discharge at an atmospheric pressure of 300 mbar. In this work, we investigate the possible plasma chemical reactions playing a role in Titan’s atmosphere. The main results that we have obtained so far are related to the production of H₂, formation of higher order hydrocarbons such as C_nH_m with n ≤ 12, and the formation of CN films on the electrodes by the fragmentation of C₂H₄/N₂ and C₂H₆/N₂ gases.
