Thermal Plasma with Super-Ideal Quenching

Maximum Value of Energy Efficiency of CO2 Dissociation in Thermal Plasma with Super-Ideal Quenching of the Dissociation Products 

Comparison of Thermal and Non-Thermal Plasma Approaches to CO2 Dissociation Comments on Products (CO-O2) 

Explosion in the CO-O2 mixture has a branching-chain nature and, once initiated, results in exponential growth of active species evenbefore the system heats up. The branching-chain explosion is based on the following elementary reactions  

This chain oxidation converts CO back into CO2 at quite low gas temperatures. Plasma-chemical dissociation in dry CO2 helps to protect products from reverse reactions.
