Selective Oxidation of Methane Using a Non-Thermal Pulsed Plasma

Abstract

Methane selective oxidation to methanol using a nonthermal pulsed plasma was investigated at room temperature and atmospheric pressure. The maximum selectivity of methanol was 47% at the methane conversion of 1.9%. It was found that the methanol selectivity is more sensitive to the input power for discharge than to oxygen concentration and discharge length. Effects of input power for discharge, oxygen concentration, and discharge length on methane conversion and selectivity of each product were investigated.
