Carbon dioxide dissociation using TM011 cavity mode atmospheric microwave plasma

Summary form only given. Carbon dioxide (CO₂) is the primary greenhouse gas that is responsible for global warming. It accounts for 84% of all US greenhouse gas emitted mainly due to fossil fuel combustion. One way to mitigate the environmental effects due to CO₂ is to dissociate it into Carbon monoxide (CO) and Oxygen (O) using atmospheric microwave plasma. Advantages of atmospheric microwave plasma include reduction in the capital cost of equipment and elimination of constraints imposed by vacuum compatibility, generation of highly active species, and electrodeless power coupling. In this paper, we present an atmospheric microwave plasma system based on a TM₀₁₁ cavity mode for CO₂ dissociation. Analytical calculations, modeling, and design of the system will be described.
