“…It is used to assess the technical solution of a design at any choice and at a design stage. Furthermore, through numerical modelling, the final results can be approached using mathematical modelling without presenting the prototypes of the fabricated physical models [1,2]. Charged particles within zinc bromine batteries cells systems anode reactors determine the reduction and the re-oxidizing of these charged metallic zinc on the anode feeder electrode.…”

Batteries will continue to encounter the problem of dendrite formation until a suitable solution is identified to address the problem. Dendrite formation can short circuit batteries cells, reduce their life span, voltages and cause mechanical abrasion to the cells. Batteries electrodes are part of the approaches that can be used to address these problems but depending on the fabrication of these electrodes and dimensions. Before fabricating and incorporating a real anode reactor to a fabricated ZnBr 2 cell system, it was necessary to model the behaviour with injected carbon particles in between 254 microns to 354 microns and simulate the geometry in COMSOL to observe their interaction with the electrolyte. This study investigates the performances of a designed anode reactor and to observe within the reactor the effect of having a uniform and non-uniform current density distribution before the fabrication, physically charge and incorporating it to the anode-side of ZnBr 2 cell system.

“…Most of these compounds are extremely harmful to the environment because of their toxicity. Therefore, considerable effort has been directed towards the treatment of XPs, especially CPs, owing to their highest toxicity among XPs [2][3][4][5][6][7][8]. On the other hand, FPs, which are used widely as the precursors for chemicals, pharmaceutics, pesticides, or fire retardant products, have been continuously entering the environment and accumulating because of their inertness.…”

Anodic contact glow discharge electrolysis (CGDE) is a DC-excited atmospheric pressure discharge, in which a steady non-thermal plasma is generated locally between the surface of an electrolytic solution and an anode in contact with it. The I-U characteristics of CGDE were investigated. The plasma temperatures were estimated to be in the range, 1373-2045 K. Hydroxyl radicals and hydrogen peroxide were the main oxidants generated by CGDE. The hydrogen peroxide concentration reached 31.2 mmol/L (mM) in a phosphate buffer solution without organic substrates. During CGDE, the DFPs and the corresponding total organic carbon (TOC) in water were consumed. Most of the fluorine atoms in the DFPs were converted to fluoride ions, and the fluoride concentration increased steadily. An analysis of the hydroxylation of DFPs suggested that the hydroxyl radicals generated by CGDE were the key species responsible for the degradation of DFPs, and the possible mechanistic routes of the mineralization of DFPs are proposed. The disappearance of DFPs and the TOC as well as the defluorination of the DFPs followed first-order kinetics. The rate of TOC disappearance was relatively constant: 1.00 ± 0.05 9 10 -2 min -1 . The order of disappearance of the DFPs was 2,6-DFP [ 2,3-DFP [ 2,5-DFP [ 2,4-DFP [ 3,4-DFP [ 3,5-DFP. In contrast, the order of defluorination of the DFPs was 2,5-DFP [ 2,3-DFP [ 2,6-DFP [ 2,4-DFP [ 3,4-DFP [ 3,5-DFP. Overall, the order of the reaction rates for each DFP was k DFP [ k dF [ k TOC .

Dayal et al (2004) apresentaram um estudo sobre a destruição de lixo químico, usando o reator a plasma, baseado na tecnologia PLASCON (PLASma-CONversion), que é usado comercialmente para destruir herbicidas, CFC e PCB. O resíduo químico foi injetado num reator a arco de plasma por corrente contínua, adicionado de gás argônio, com objeto de encontrar o melhor formato de reator para máxima DRE (destruction and removal efficiency).…”
