Modeling of Plasma Reforming of Ethanol into Hydrogen in the Electric Discharge in a Gas Channel with Liquid Wall

Abstract

This paper presents the results of the theoretical study of the process of low-temperature plasma-assisted reforming of ethanol into molecular hydrogen in the electric discharge in a gas channel with liquid wall (DGCLW) in the regime where the discharge is ignited by the breakdown with the air injection between tubular electrodes and then it burns in the ethanol-water mixture self-sustainingly without air supply. The numerical modeling clarifies the nature of non-thermal conversion and explains the kinetic mechanism of nonequilibrium plasma-chemical transformations in the gas-liquid system and evolution of hydrogen during the reforming as a function of discharge parameters and ethanol-water ratio in the mixture.
