Regeneration of spent activated carbon by wet air oxidation

摘要: The regeneration of activated carbon was studied using the wet air oxidation process in temperature range 150–240°C and oxygen partial pressure 0.2 to 1.0 MPa. Phenol used as substrate. overall mechanism has been analysed different steps taking place during were individually investigated. Kinetics phenol mass transfer coefficients have estimated ranges studied. Oxidative degeneration characteristics also conditions found at which extent is favourable. On a etudie la du charbon actif au moyen d'un procede d'oxydation humide des temperatures comprises entre 150 et 240°C pressions partielles d'oxygene variant de 0,2 1,0 On utilise comme substrat. Le mecanisme global ete analyse on separement les differentes etapes marquant le processus regeneration. La cinetique transfert matiere l'oxygene ont estimes dans gammes etudiees. egalement caracteristiques degenerescence oxydante actif. Les pression determinees degre est favorable.
