Upgrading ash - rich activated carbon from distilled spirit lees / Juan Yang in Industrial & engineering chemistry research, Vol. 51 N° 17 (Mai 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 17 (Mai 2012) . - pp. 6037–6043 Titre : Upgrading ash - rich activated carbon from distilled spirit lees Type de document : texte imprimé Auteurs : Juan Yang, Auteur ; Jian Yu, Auteur ; Wei Zhao, Auteur Année de publication : 2012 Article en page(s) : pp. 6037–6043 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : steam  activated  carbon Résumé : Activated carbon (AC) was prepared from ash-rich distilled spirit lees via carbonization and successive activation incorporated with different deashing methods. The results show that the alkali treatment of the steam-activated carbon (ATAC) produced the AC with the highest performance in comparison with the NaOH activation and direct alkali treatment of the carbonized carbon (ATCC). The ATAC removed 84.4% of the ash from steam-activated carbon and increased the BET surface area and total pore volume by 92.3% and 109.3%, respectively, resulting in the AC with its ash content of 11 wt %, BET surface area of 620 m2/g, and total pore volume of 0.67 cm3/g. The article also revealed that it is possible to use the alkaline leaching solution from the ATAC, which is mainly composed of sodium silicate, as the major binder to mold the produced powder AC.
