The gliding arc discharge is a plasma discharge at room temperature under atmospheric pressure , it also has a balance and non - balance , in which the former guarantees that the amount of processing , the latter to ensure the efficiency of chemical reaction . Therefore, the gliding arc discharge used in methane reforming , has good prospects , but the energy consumption to be reduced . The gliding arc discharge plasma reforming of methane to conduct systematic research emphasis on the variety of oxidants, air flow , and discharge voltage parameters of methane reforming , and catalytic collaborative gliding arc discharge restructuring , AC gliding arc chopping , rotating gliding arc process improvements are discussed . The results show that when carbon dioxide as an oxidant , gliding arc discharge restructuring has significantly improved test results than the thermodynamic equilibrium , but the energy consumption is still high ; When using oxygen restructuring analog biogas , the addition of oxygen is not conducive to reducing energy consumption ; when the steam reforming of methane using oxygen and water , adding a small amount of water vapor can be improved reforming effect , while the oxygen on the appropriate insufficient amount , the lowest energy consumption . Improve the discharge voltage, discharge power increases, and can promote the reforming . While energy consumption first decreases and then increases with increasing flow . Using catalytic synergistic gliding arc discharge , due to the catalyst on the selective partial oxidation of methane , can effectively promote methane, as well as the conversion of ethylene, acetylene , and significantly reduce power consumption . The AC chopper gliding arc discharge , when chopping into a half-wave , has the lowest energy consumption , but the overall effect was not significant . The rotation sliding arc discharge reformer on the basis of the rotating arc , due to partial oxidation of the acetylene, ethylene , and the like formed by the intense combustion flame , ultimately promoting the conversion of methane and hydrogen generated , while the energy consumption is significantly reduced .
