Catalytic wet air oxidation of phenolic compounds and mixtures over activated carbon / Catherine Ayral in Industrial & engineering chemistry research, Vol. 49 N° 21 (Novembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 21 (Novembre 2010) . - pp. 10707-10714 Titre : Catalytic wet air oxidation of phenolic compounds and mixtures over activated carbon : Conversion, mineralization, and catalyst stability Type de document : texte imprimé Auteurs : Catherine Ayral, Auteur ; Carine Julcour Lebigue, Auteur ; Frank Stuber, Auteur Année de publication : 2011 Article en page(s) : pp. 10707-10714 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Stability  Catalyst  Mineralization  Activated  carbon  Oxidation  Wet  air  Catalytic  reaction Résumé : Catalytic wet air oxidation (CWAO) of phenolic compounds over three activated carbons (ACs) has been investigated in a semibatch autoclave to better understand the influence of AC properties on the efficiency and stability of CWAO. Phenol, 4-nitrophenol, 4-chlorophenol, and 4-hydroxybenzoic acid, as well as synthetic mixtures comprising two to four of the aforementioned molecules, have been chosen as model pollutants to evaluate synergy or competition effects. To this end, the amount of pollutant(s) (re)adsorbed on AC during a preliminary adsorption step, the pollutant conversion, and the mineralization yield obtained during CWAO as well as the AC stability upon recycling are compared for each case.
