    Abstract

    Selective formation of C 2H 2 and/or CO was achieved using a periodic pulsed spark discharge, with and without catalysts, at room temperature. The selective formation of C 2H 2 with high conversion was achieved. A 49% yield of C 2H 6 was obtained in Pt/SiO 2 and discharge combined system. With the increased of CO 2 content, C 2 selectivity decreased sharply, while CO selectivity increased drastically. Under the condition of high CH 4 concentration, the formation of C 2H 2 was predominant whereas under the condition of high CO 2 concentration, CO became the main product. The use of pretreated NiMgO solid solution catalyst increased CO selectivity to 85% at CH 4/CO 2 = 1:1, while no remarkable effect was observed without pretreated catalysts. The pulsed spark discharge reaction of CH 4 in the presence of O 2 produced CO and C 2H 2 at room temperature while suppressing carbon deposition and CO 2 formation.
