A Comprehensive Chemical Model for the Splitting of CO₂ in Non‐Equilibrium Plasmas

Abstract

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.

Data Needs for Modeling Low-Temperature Non-Equilibrium Plasmas: The LXCat Project, History, Perspectives and a Tutorial

“…This can be used to parameterize all the above electron transport coefficients and rate coefficients (in look-up tables) as functions of mean energy, disregarding the corresponding E/N values, so that they can be compared with their "Maxwellian" counterparts. Fluid or global models [30][31][32][33] based on this approach contain a fluid energy equation to describe the evolution of the mean energy¯ ( r, t) without assuming it directly related to E/N, similar to the thermal fluid models based on a Maxwellian distribution function. This is known as the "local mean energy approximation", in contrast to the "local field approximation" where the transport coefficients and rate coefficients are explicitly dependent on E/N.…”

CO2 Conversion in a Gliding Arc Plasmatron: Elucidating the Chemistry through Kinetic Modeling

“…The chemistry set used in this study is based on the original model of Kozák et al 11 which has been thoroughly reviewed by Koelman et al 39 . The electron impact reaction rate constants are calculated using a pre-evaluated electron energy distribution function (EEDF;…”

Plasma-enhanced catalysis for the upgrading of methane: a review of modelling and simulation methods

“…Nonetheless, nowadays solvers embedded within commercial software (e.g. COMSOL and PLASIMO) or distributed as freeware (BOLSIG+, 89 EEDF, 90 and LoKI 91 ) are available and are used routinely by the research community, 28,37,92 so that the assumption of an ideal theoretical distribution, such as that of Maxwell or Druyvesteyn, is no longer required. Figure 1 compares the Maxwell and Druyvesteyn electron energy distribution functions for a pure methane plasma with those obtained using different freely available Boltzmann equation solvers at a mean electron energy of 5 eV.…”
