Influence of a Gas Injection Direction on the Reforming Performance in a Bipolar Pulse-Driven Plasma Reactor Operating at Atmospheric Pressure

摘要

Hydrogen production from methane reforming using the partial oxidation reaction is carried out using a bipolar pulse-driven plasma reactor operating at atmospheric pressure. The influence of axial and radial injections of CH₄ and O₂ on the reforming performance is investigated in conjunction with the spatial distribution of their spectral emissions by varying the O₂/C ratio at a fixed discharge power. With increasing the O₂/C ratio, the axial injection achieves the better conversion and efficiency. The measurement of spectral emissions reveals that the higher efficiency of axial injection is caused by its efficient use of oxidation reaction heat.
