Direct synthesis of C4 hydrocarbons from methane using dielectric barrier discharge method
For the purpose of the selective synthesis of C4 hydrocarbons from methane under atmospheric pressure, reaction mechanism during the non-equilibrium plasma state generated by a dielectric barrier discharge (DBD) and utilization of intermediate component were investigated. Generated plasmas are suitable for carbon-chain growth reactions due to the periodic discharge, and methane is mainly converted to ethane and propane with small amounts of unsaturated hydrocarbons. However, the superiority of the progress of carbon-chain growth reaction cannot overcome the disadvantage that the product distribution spreads widely and the selectivity of wanted-product lowers. Therefore, a control technique for product distribution obtained by plasma reactions using DBD method is developed for the utilization as the chemical reaction field. In this study, the effects of feed-gas species and hydrogen addition into feed-gas on the production rate of C4 hydrocarbons were investigated. The selectivity for C4 hydrocarbons was increased with an increase in molar fraction of hydrogen. Furthermore, higher yield of C4 hydrocarbons, especially n-C4H10, was obtained by hydrogen addition to C2H4.
