Title:
DEVICE AND METHOD FOR GAS TREATMENT USING LOW-TEMPERATURE PLASMA AND CATALYST MEDIUM
Document Type and Number:
WIPO Patent Application WO/2013/042328
Kind Code:
A1
Abstract:
[Problem] To provide a device and a method for oxidation decomposition treatment of a hazardous gas of a volatile organic compound (VOC) or the like at normal temperature. [Solution] A gas treatment device characterized in being provided with a plasma-generating unit and a catalyst medium. The plasma-generating unit is provided with at least a flow channel through which a gas to be treated flows; and a power-supply unit for supplying electrical power, a first electrode, a second electrode, and a dielectric material arranged inside the flow channel. A voltage is impressed between the first electrode and the second electrode by the power-supply unit and electrical discharging is caused to occur, whereby plasma is generated. The catalyst medium is adapted for accelerating a reaction with the gas to be treated and is provided in a position where the plasma generated by the plasma-generating unit inside the flow channel is present, wherein the catalyst medium has metallic catalytic particles present on an inorganic substance.
