  The conventional ways of processing natural gas into more efficient and
economical fuels usually either have low conversion rate or low energy
efficiency. In this work, a new approach of methane liquefaction is proposed.
Instead of direct treatment of only natural gas, plasma activated methane is
reacting with liquid fuel. In this way, methane molecules are directly
incorporated onto liquid fuel to achieve liquefaction. Nanosecond-pulsed
dielectric barrier discharge and atmospheric pressure glow discharge are used
here to ensure no local heating in gas bubbles. Effects of both discharges on
methane reaction with liquid fuel are investigated, mass and chemical changes
in liquid are observed. Preliminary results show fixation of methane in liquid
fuel.
