- This paper focuses on the dissociation of carbon dioxide (CO ) following the absorption processes of microwave radiation by noncontact metal wire (tungsten). Using a microwave plasma generator (MPG) with a single-mode cavity, we conducted an interaction of microwaves with a noncontact electrode in a CO atmosphere. High energy levels of electromagnetic radiation are generated in the focal point of the MPG's cylindrical cavity. The metal wires are vaporized and ionized from this area, subsequently affecting the dissociation of CO The CO dissociation is highlighted through plasma characterization and carbon monoxide (CO) quantity determination. For plasma characterization, we used an optical emission spectroscopy method (OES), and for CO quantity determination, we used a gas analyzer instrument. Using an MPG in the CO atmosphere, we obtained a high electron temperature of the plasma and a strong dissociation of CO . After 20 s of the interaction between microwaves and noncontact electrodes, the quantity of CO increased from 3 ppm to 1377 ppm (0.13% CO). This method can be used in space applications to dissociate CO and refresh the atmosphere of closed spaces.
