“…This is not so practical for high-throughput processing of exhaust gases. Increasing the pressure leads, however, to a clear reduction in the energy efficiency [6,36,37], although at atmospheric pressure, a CO 2 conversion of 45% 40 with an energy efficiency of 20% were recently reported [37], which is still better than the results obtained with a DBD plasma.…”

This paper discusses our recent results on plasma-based CO2 conversion, obtained by a combination of experiments and modeling, for a dielectric barrier discharge (DBD), a microwave plasma and a packed bed DBD reactor. The results illustrate that plasma technology is quite promising for CO2 conversion, but more research is needed to better understand the underlying mechanisms and to further improve the capabilities.

“…1. Although several works have studied CO * 2 chemistry [4][5][6][7][8][9][10][11][12][13], a detailed reaction mechanism for the formation and destruction of CO * 2 does not exist, and arguably CO * 2 chemical kinetics are not as well studied as OH * and CH * kinetics. Therefore the primary focus of the present study was to verify specific wavelengths that isolate the CO * 2 chemiluminescence, develop a working chemical kinetics mechanism for CO * 2 , and compare this mechanism to new shock-tube results.…”

Chemiluminescence experiments have been performed to assess the state of current CO * 2 kinetics modeling. The difficulty with modeling CO * 2 lies in its broad emission spectrum, making it a challenge to isolate it from background emission of species such as CH * and CH 2 O * . Experiments were performed in a mixture of 0.0005H 2 + 0.01N 2 O + 0.03CO + 0.9595Ar in an attempt to isolate CO * 2 emission. Temperatures ranged from 1654 K to 2221 K at two average pressures, 1.4 and 10.4 atm. The unique time histories of the various chemiluminescence species in the unconventional mixture employed at these conditions allow for easy identification of the CO * 2 concentration. Two different wavelengths to capture CO * 2 were used; one optical filter was centered at 415 nm and the other at 458 nm. The use of these two different wavelengths was done to verify that broadband CO * 2 was in fact being captured, and not emission from other species such as CH * and CH 2 O * . As a baseline for time history and peak magnitude comparison, OH * emission was captured at 307 nm simultaneously with the two CO * 2 filters. The results from the two CO * 2 filters were consistent with each other, implying that indeed the same species (i.e., CO * 2 ) was being measured at both wavelengths. A first-generation kinetics model for CO * 2 and CH 2 O * was developed, since no comprehensively validated one exists to date. CH 2 O * and CH * were ruled out as being present in the experiments at any measurable level, based on calculations and comparisons with the data. Agreement with
