摘要	A conventional high voltage wire-like plasma can be greatly enhanced and spread by pulsed microwave to form an umbrella-like plasma continuously distributed in reactor. By use of this plasma, methane is directly converted to C-2 hydrocarbons at high yield under the condition of atmospheric or higher pressure. The effect of pressure, microwave power, pulse duration, molar ratio of H-2/CH4 and flow rate on the methane conversion was investigated. Higher conversion of methane is achieved by proper choice of parameters, and the products only comprise ethylene and acetylene; The molar ratio of C2H2/C2H4 could be adjusted through changing the pressure. With total flow rate of 300 mL/min, H-2/CH4 molar ratio of 2, pressure of 0.13 MPa, peak microwave power of 120 W, pulse duty factor of 400/400 ms, conversion of methane and yield of C-2 could reached up to 59.2% and 52% respectively.
