Boudouard reaction driven by thermal plasma for efficient CO2 conversion and energy storage

Conversion of CO2 by non- thermal inductively-coupled plasma catalysis

“…These theoretical studies also aim to make a connection to CO2 conversion by electrochemical ways, see for instance [29,30]. A very different catalytic approach is to use the Boudouard reaction to enhance the CO yield [31]. Both enhanced theory and the Boudouard reaction have not yet been applied to RF-ICP conversion.…”

“…In blue are the data points compiled by Snoeckx and Bogaerts, 20 also shown in Fig. 6; red are data by the Yin group using a thermal arc and a solid C target; 50,69 purple are the results by Bermudez et al 70 using the Boudouard reaction driven by microwave heating of a solid C reactant in a CO 2 flow; black are the data on the Boudouard reaction driven by microwave or thermal heating of solid C by Hunt et al way increases the CO yield from this RF reactor. We note that the role of the carbon is not that of a catalyst, because the carbon is consumed in the reaction.…”

“…8a. 50 The device consists of a cathode chamber with Ar gas inlet 1 for starting and maintaining the discharge and protecting the cathode from carbon contamination by CO 2 . The arc flows into a second chamber with gas inlet 2 to inject CO 2 in the plasma flow.…”

“…8b. 50 In experiments labeled Mode 1 in Fig. 14 Ar is injected through gas inlet 1, N 2 through inlet 2 and CO 2 through inlet 3.…”

“…The equipment used has been described earlier in a number of papers. 26,50,[72][73][74][75][76][77] In some of these experiments catalysts were placed in the reactor inside the RF coils. 76 In the same way as for the catalysts we have inserted carbon, confined by a Cu mesh.…”
