Gas-Phase Plasma Decomposition Processes

The endothermic plasma-chemical process of carbon dioxide decomposition, illustrated in Fig. 5-1, can be presented by the summarizing formula [Pg.259]

The enthalpy of the process is fairly high and close to that corresponding to hydrogen production from water. The total decomposition process (5-1) starts with and is limited by CO2 dissociation  [Pg.259]

Combination of reactions (5-1) and (5-3) together with recirculation of CO2 results in the two-stage cycle of hydrogen production from water, which is of special interest in the [Pg.259]

Major Experimental Results on CO2 Dissociation in Different Plasma Systems and Energy Efficiency of the Process [Pg.260]

CO2 dissociation was investigated in numerous thermal and non-thermal plasma systems. The most critical point in the experiments was the maximization of the energy efficiency of the process (5-1), r], determined by the ratio of the dissociation enthalpy AH = 2.9eV/mol to the actual energy cost Eco of one CO molecule produced in a plasma system  [Pg.260]
