摘要

Microdischarges in atmospheric pressure H_2O/SO_2 gas mixture at high temperature are studied to evaluate their plasma-chemical reactivity to produce hydrogen gas. The microplasma is generated inside a porous ceramic (MIPC) covered with two steel meshes as the gas mixture at atmospheric pressure flows through the medium. Voltage-current characteristics and optical emissions are measured to determine the electrical properties of the DC discharge and the degree of non-equilibrium. The discharge current at a given voltage substantially increases as the gas temperature is increased, thus posing a possibility to reduce the electrical power needed to sustain the discharge. The study also showed the possibility of facilitating the reaction between H_2O and SO_2 not by electrocatalyst like platinum but by non-thermal electrons.
