“…Consideration into separation of all the product gases requires further work and is outside the scope of the article. This is in contrast to the works of Heijkers et al (2015) who observed effective conversions up to 15% of N2 to other products, although in that work the specific energy input (SEI) peaked at 7.1 eV/molecule compared to the maximum of 0.43 eV/molecule used in this work.…”

Integrated CO2 Capture and Utilization Using Non-Thermal Plasmolysis

In this work, two simple processes for carbon dioxide (CO2) such as capture and utilization have been combined to form a whole systems approach to carbon capture and utilization (CCU). The first stage utilizes a pressure swing adsorption (PSA) system, which offers many benefits over current amine technologies. It was found that high selectivity can be achieved with rapid adsorption/desorption times while employing a cheap, durable sorbent that exhibits no sorbent losses and is easily regenerated by simple pressure drops. The PSA system is capable of capturing and upgrading the CO2 concentration of a waste gas stream from 12.5% to a range of higher purities. As many CCU end processes have some tolerance toward impurities in the feed, in the form of nitrogen (N2), for example, this is highly advantageous for this PSA system since CO2 purities in excess of 80% can be achieved with only a few steps and minimal energy input. Nonthermal plasma is one such technology that can tolerate, and even benefit from, small N2 impurities in the feed, therefore a 100% pure CO2 stream is not required. The second stage of this process deploys a nanosecond pulsed corona discharge reactor to split the captured CO2 into carbon monoxide (CO), which can then be used as a chemical feedstock for other syntheses. Corona discharge has proven industrial applications for gas cleaning and the benefit of pulsed power reduces the energy consumption of the system. The wire-in-cylinder geometry concentrates the volume of gas treated into the area of high electric field. Previous work has suggested that moderate conversions can be achieved (9%), compared to other non-thermal plasma methods, but with higher energy efficiencies (>60%).

“…Furthermore, as the gas content contains more N2, a higher energy requirement is needed to ignite and sustain the plasma, and more energy is directed toward reactions of N-containing species and diverted away from CO2 dissociation. This effect becomes dominating as more N2 is added as demonstrated in other works (Heijkers et al, 2015).…”

“…We developed a 0D chemical kinetics model for different gas mixtures relevant for CO 2 conversion, i.e., pure CO 2 [15,[48][49][50], CO 2 /CH 4 [16,17] and CO 2 /N 2 [51], 30 but here we only show results for pure CO 2 . Table 1 gives an overview of the species included in the pure CO 2 model.…”

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.

An extensive CO2 plasma model is presented that is relevant for the production of “solar fuels.” It is based on reaction rate coefficients from rigorously reviewed literature, and is augmented with reaction rate coefficients that are obtained from scaling laws. The input data set, which is suitable for usage with the plasma simulation software Plasimo (https://plasimo.phys.tue.nl/), is available via the Plasimo and publisher's websites. The correctness of this model implementation has been established by independent ZDPlasKin implementation (http://www.zdplaskin.laplace.univ-tlse.fr/), to verify that the results agree. Results of these “global models” are presented for a DBD plasma reactor.
