Modeling Photocatalytic Reactions Model pollutants

Three-dimensional CFD-coupled with radiation field modeling and photocatalytic reaction dynamics was employed by Salvado-Estivill et al. (2007b) to model the decomposition of TCE in a flat-plate, single-pass photocatalytic reactor containing immobilized P25. The outcome was pollutant-specific kinetic rate parameters, which were independent of the reactor geometry, radiation field, and fluid dynamics. This was followed by... 

Modeling photocatalytic reaction processes requires careful consideration of reaction and adsoiption phenomena. In order to establish the importance of these matters, experiments can be developed using model pollutants such as methylene blue, phenol, 2-chlorophenol, 2,4-dichlorophenol, catechol (or 1,2 benzenediol), andpyrogallol (or 1,2,3 benzenetriol), each having quite different behaviours of adsorption and reaction. 

Chin et al. (2007b) used pseudo-first order reaction kinetics combined with the ideal continuous stirred tank reactor (CSTR) model to evaluate the effect of initial concentration of pollutant on the performance of a submerged membrane photocatalytic reactor for the degradation of bisphenol A in water (Equation [21.2]) ...
