Deactivation by filamentous carbon formation on Co/aluminum phosphate during Fischer-Tropsch synthesis / Jong Wook Bae in Industrial & engineering chemistry research, Vol. 48 N° 6 (Mars 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 6 (Mars 2009) . - pp. 3228–3233 Titre : Deactivation by filamentous carbon formation on Co/aluminum phosphate during Fischer-Tropsch synthesis Type de document : texte imprimé Auteurs : Jong Wook Bae, Auteur ; Seung-Moon Kim, Auteur ; Seon-Ju Park, Auteur Année de publication : 2009 Article en page(s) : pp. 3228–3233 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Amorphous  aluminum  phosphate  Cobalt  catalysts  Fischer-Tropsch  synthesis Résumé : Amorphous aluminum phosphate (AlPO4)-supported cobalt catalysts, with and without Ru promotion, were evaluated to study CO hydrogenation activity during Fischer−Tropsch synthesis (FTS). The Ru-promoted catalyst (RuCo/AlPO4) exhibited higher CO conversion and C8+ selectivity than that of the unpromoted catalyst (Co/AlPO4) and Co/Al2O3 catalyst. Interestingly, filamentous carbon was formed, even at the mild FTS reaction conditions (T = 220−240 °C and P = 2.0 MPa), on Co/AlPO4, and it eventually accelerated catalyst deactivation. The presence of an Ru promoter restricted the formation of filamentous carbon and enhanced catalyst stability.
