On the plasma system for CO2 dissociation

Summary form only given. The CO₂ capture and storage technology (CCS technology) needs immediate action, but does not have complete solutions yet due to the efficient, and economical CO₂ conversion problems.In this presentation, the governing fundamental quantities will be identified to obtain the maximum energy efficiency and capacity for CO2 dissociation. Several CO2 conversion ideas will be introduced, describing the advantages and disadvantages of each conversion techniques. The plasma reactor has been known as one of the most promising candidate for CO2 dissociation. However, the problems on how to achieve high efficiency, stable discharge at atmospheric pressure, and reliability at high power density should be solved. The ICP(Inductively coupled plasma) source will be introduced along with other sources such as microwave, DBD (dielectric barrier discharge), and DC for the efficient CO2 dissociation. In this presentation, the technical issues for the mass production of CO2 conversion also will be discussed.
