Mechanism and kinetics of sulfite oxidation in the presence of ethanol / Li-Dong Wang in Industrial & engineering chemistry research, Vol. 48 N° 9 (Mai 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 9 (Mai 2009) . - pp. 4307–4311 Titre : Mechanism and kinetics of sulfite oxidation in the presence of ethanol Type de document : texte imprimé Auteurs : Li-Dong Wang, Auteur ; Yong-Liang Ma, Auteur ; Ji-Ming Hao, Auteur Année de publication : 2009 Article en page(s) : pp. 4307–4311 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Sulfite  oxidation  Ethanol  Oxidation  kinetics Résumé : Oxidation of sulfite is an important process in flue gas desulfurization. The inhibitory effects of four inhibitors on the intrinsic oxidation of sulfite were compared, and ethanol was found to be an excellent inhibitor. The intrinsic oxidation kinetics of sulfite in the presence of ethanol used as an inhibitor was investigated using a batch apparatus. The reaction orders of the reagents and the activation energy were obtained. The results indicate that the intrinsic reaction proceeds in two steps: rapid reaction in an oxygen-rich state and slow reaction in an oxygen-depleted state. Integrated with the macroscopic oxidation kinetics of calcium sulfite in the presence of an ethanol inhibitor, it was concluded that the macroscopic oxidation process is controlled by the intrinsic reaction rate and the intrinsic oxidation reaction proceeds in the rapid reaction state. Furthermore, a mechanism for the intrinsic reaction is proposed based on a steady-state assumption. The results derived with this mechanism are in good agreement with the experimental results.
