Using bubbling apparatus, the kinetics of oxidation of total sulfite in ammonia-based wet flue gas desulfurization (FGD) process was investigated by varying concentrations of SO 32− and SO 42− , pH, temperatures and air flow. The concentration range of sulfite is 0.0044–0.026gmolL −1 and that of sulfate is 0.5–2gmolL −1 . Experiments were conducted at pH level...
The aqueous noble metal catalysed alcohol oxidation is a reaction which can profitably be applied in fine-chemistry and for carbohydrate conversion. In this paper engineering aspects of this reaction are treated, i.e. the reaction kinetics, oxygen mass transfer restrictions, catalyst deactivation and reactivation, and implications for reactor design and operation.First a reaction mechanism is proposed,...
