Selective formation of C2H2 and/or CO was achieved using a periodic pulsed spark discharge, with and without catalysts, at room temperature. The selective formation of C2H2 with high conversion was achieved. A 49% yield of C2H6 was obtained in Pt/SiO2 and discharge combined system. With the increased of CO2 content, C2 selectivity decreased sharply, while CO selectivity increased drastically. Under the condition of high CH4 concentration, the formation of C2H2 was predominant whereas under the condition of high CO2 concentration, CO became the main product. The use of pretreated NiMgO solid solution catalyst increased CO selectivity to 85% at CH4/CO2 = 1:1, while no remarkable effect was observed without pretreated catalysts. The pulsed spark discharge reaction of CH4 in the presence of O2 produced CO and C2H2 at room temperature while suppressing carbon deposition and CO2 formation.
