COMBUSTIBLE SYNGAS PRODUCTION APPARATUS AND METHOD FROM CARBON DIOXIDE USING MICROWAVE PLASMA-CATALYST HYBRID PROCESS

摘要

The present invention relates to an apparatus and a method for manufacturing combustible syngas from carbon dioxide, which is greenhouse gas, using a high-temperature microwave plasma-catalyst hybrid process. More particularly, the present invention generates a high-temperature plasma flame, of which the temperature is thousands of degrees, by supplying a plasma-generating device with carbon dioxide and a small amount of methane to be used as plasma-generating gas and fuel, and forms combustible syngas including hydrogen and carbon monoxide by forming a large amount of activated radicals that are in reaction-accelerating state owing to the generated plasma, and conducting reforming reaction at high temperature. In addition, radicals and ions generated from non-reacted carbon dioxide and methane by plasma accelerates conversion into combustible syngas using a catalyst in a catalytic reaction chamber installed at the end of a plasma reaction chamber, which is the end of the plasma flame, to intercommunicate, and reaction and combustible gas yield rate are improved by supplying the used catalyst to a catalyst regenerating chamber, regenerating the catalyst via combustion and re-supplying the catalyst to the catalytic reaction chamber to conduct catalytic reaction.
