A review and comparison of the reaction kinetics of the catalytic oxidation of PCDD/Fs and model compounds

Due to convenience and toxicity, the development of active catalysts for catalytic oxidation polychlorinated dibenzo-p-dioxins dibenzofurans (PCDD/Fs) typically relies on research conducted model compounds in place PCDD/Fs. The comparability between experiments PCDD/Fs is however unresolved, questioning design PCDD/F removal by conducting with compounds. For this reason, current literature destruction reviewed analyzed. A review reaction kinetics indicates that similar effects are induced changes gas phase composition, few deviations. Based kinetics, a first-order rate expression respect or compound was selected used extract activation energies (Ea) constants at 200 °C (k200) 5 data sets 265 It found V2O5/TiO2-based most studied catalyst formulation generally achieve higher k200 than other non-precious metal formulations. Comparing kinetic parameters different reveals has significantly lower Ea compared commonly evident more laboratory required order establish relevance using optimizing oxidation, whereas it established only can be developed actual realistic operating conditions.
