Study on Natural Gas Converted to C2 Hydrocarbons in Plasma State
This paper presents the methane coupling with a new developed rotary multidentate helix electrode under plasmas at atmospheric pressure and in the presence of hydrogen to investigate the effects of peak voltage input the electric fields and feed flow rate on CH4 conversion and C2 yield and selectivity. The best result without remarkable amount of coke is 69.85% of single pass yield of C2 hydrocarbons with 70.46% of CH4 conversion and 99.14% of selectivity of C2 hydrocarbons. The emission of excited species such as excited radicals and atoms (C,CH,C2,H and H2) were detected in the spectra range of 300 nm～700 nm.
