Kinetics and simulation including mass-transfer processes of direct H2O2 synthesis from H2 and O2 over Pd/C catalyst in water containing H+ and Br− Ions / Takashi Deguchi in Industrial & engineering chemistry research, Vol. 50 N° 8 (Avril 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 8 (Avril 2011) . - pp. 4351–4358 Titre : Kinetics and simulation including mass-transfer processes of direct H2O2 synthesis from H2 and O2 over Pd/C catalyst in water containing H+ and Br− Ions Type de document : texte imprimé Auteurs : Takashi Deguchi, Auteur ; Masakazu Iwamoto, Auteur Année de publication : 2011 Article en page(s) : pp. 4351–4358 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Kinetics  Mass  transfer  processes Résumé : Kinetic analysis including mass-transfer processes of the title reaction was carried out on the basis of the effects of the solution agitation rate, reaction time, and H2 and O2 partial pressures. The suggested equations were found to be in sufficient agreement with the experimental values. The reactions were then simulated to reveal the chemical engineering characteristics, as well as the process performance under practical reaction conditions. It follows that the reduction of the H2O2 destruction rate is highly desired and the mass-transfer coefficient of H2 (kLa) must be dramatically raised from 560 h−1, the value observed in the present experiments, for practical application of the technology. The effects of total pressure and other parameters are also discussed.
