Methane conversion was studied with electric field enhanced plasma (EFEP) technique at the atmosphere pressure and low temperature ranging from 323 K to 373 K. The conversion of methane is up to 60%-80%.The kinetics of methane conversion was studied using microreactor. The reaction model of power function type was obtained as: r = 90.99exp (-26980/RT)C0.226A(mol.m-3.s-1). The global kinetics parameters were calculated by the variable simple-pure shape method. The calculating results are in good agreement with experimental data.
