Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N° 15 (Août 2009) . - pp. 7110–7116 Titre : Porous carbon obtained by carbonization of PET mixed with basic magnesium carbonate : pore structure and pore creation mechanism Type de document : texte imprimé Auteurs : Jacek Przepiórski, Auteur ; Justyna Karolczyk, Auteur ; Kazuhiro Takeda, Auteur Année de publication : 2009 Article en page(s) : pp. 7110–7116 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Porous carbon PET [poly(ethylene terephtalate)]Magnesium carbonate mixture Gas flow Résumé : Porous carbon materials were prepared by heating of a PET [poly(ethylene terephtalate)] and magnesium carbonate (3MgCO3·Mg(OH)2·3H2O) mixture under Ar gas flow, followed by acid washing. The inorganic component of the mixture underwent thermal decomposition with formation of MgO and evolution of gaseous products including CO2 and H2O. Influence of the magnesium compound mixed with PET, and carbonization temperature on the pore structure of carbonaceous material is presented. As found, porosity of prepared materials depended on magnesium carbonate loading in the starting mixture and on heating temperature. The impact of CO2 and H2O evolved during heating on the pore structure is discussed, and a mechanism of pore formation is proposed.
