Plasma parameters, such as electron density, along with the rotational, vibrational, and excitation Ziritaxestat Inhibitor temperatures within this zone. Gas chromatography was made use of to study the decomposition of CO2 plus the formation of CO and O2 compounds. The feed and exhaust gases have been analyzed working with a compact-gas chromatograph (CGC) sort GC, Agilent 6890 N, equipped using a flame ionization detector (FID) and also the packed GC columns Molecular Sieve 139 (MS-139) and HayeSep sort Q and N. The FID can evaluate hydrocarbons for example propane, acetylene, ethylene, ethane, and other folks. Additionally, a thermal detector connected by columns, was made use of to analyze the gas elements like CO2 , CO, O2 , and so on. 2.2. Two-Dimensional Fluid Model two.two.1. Model Equations For modeling purposes, half from the AC-PPP reactor was viewed as and azimuthal symmetry about the reactor axis was assumed. Thus, the spatial description from the challenge was mathematically two-dimensional (with only axial and radial directions). The simulated domain was the discharge gap involving the high-voltage (HV) and ground electrodes. This domain was extended in to the conductive inlet/outlet pipes that will influence the electric field distribution (see Figure 3). The grid size was 4.five . The spatial and temporal macroscopic description on the gas discharge inside the reactor was determined by solving the fluid continuity equations for distinctive species coupled with Poisson’s equation. These equations had been solved working with the finite element technique (FEM). The continuity equation for each of the formed species inside the AC reactor is expressed as follows [14]: ni = Ri,m (1) t mAppl. Sci. 2021, 11,five ofAppl. Sci. 2021, 11, x FOR PEER REVIEWwhere ni could be the number density, i expresses the flux for the species i, and Ri,m are the reaction prices involving species i and species m.5 ofFigure 3.

For some reactions, the experimental data for these reaction prices have been available exactly where ni is definitely the quantity density, i expresses the flux for the species i, and Ri,m are the in the literature [16]. In other instances, the reaction rate constants had been calculated applying reaction prices among sections i and species m. the total collision cross species in terms of the collisional energy, , by the following To get a typical relationship [17]: reaction among species 1 8 1/2 -/k B T e (2) k(T ) = d (4) k B T B TFor a standard reaction amongst speciesthe reaction rate is determined by the density of each and every species, nA and nB.
