Development of a model for the wet air oxidation of phenol based on a free radical mechanism

Carbon materials and catalytic wet air oxidation of organic pollutants in wastewater

“…The mechanism postulated a heterogeneous initiation step on the catalyst surface followed by a homogeneous propagation and either heterogeneous or homogeneous termination reactions. Recent efforts by Rivas et al [216] were driven to develop more detailed radical based networks for the WAO of phenol. These models established several tens of radical reactions and should be more reliable when extrapolated beyond the conditions considered in data fitting.…”

Wet air oxidation of nitrobenzene enhanced by phenol

“…As for WAO, the reactions generally proceed according to a free-radical mechanism. During the initiation period, the free-radical concentration increases gradually until propagation becomes the dominant process, and then the reaction proceeds rapidly (Rivas et al, 1998). Phenol is a relatively more easily oxidisable organic molecule, and the free radicals Å OH, PhOO Å and Å HO 2 formed in the initiation period provide the source to initiate the oxidation of nitrobenzene.…”

Status and Prospects of Concentrated Organic Wastewater Degradation

“…Some examples of the different types of free-radical chemical reactions that can occur are showed by Eqs. 1-26 (Mantzavinos et al, 1997;Ingale et al, 1996;Robert et al, 2002;Rivas et al, 1998;Emanuel et al, 1980;Wakabayashi & Okuwaki, 1988;Eyer, 2001;Li et al, 1991;Farhataziz & Ross, 1977;Patterson et al, 2001;Glaze et al, 1995;Ichinose, S.;Okuwaki, 1990 ): …”
