The DC pulse discharge technology was utilized in non-catalytic direct conversion of CH4 under ambient temperature and 1 atm. Acetylene was produced with 95% selectivity. Though CH4 conversion increased depending on the number of irradiated pulse and the distance of electrodes, the selectivity was almost constant. A study on the effect of the coexisting gas in removing deposited carbon from the discharge region showed that oxygen was most effective. CO was a by-product, but CO2 was not produced. Even under oxygen coexisting condition, acetylene selectivity was kept constant under any CH4 conversion. Reforming of CH4 with CO2 or steam also proceeded with this technology. The catalytic reaction with discharge is currently being investigated. Original is an abstract.
