Removal of thiophene from coking benzene over SO42−/Fe2O3 solid acid under mild conditions / Zhanjiang Kang in Industrial & engineering chemistry research, Vol. 48 N° 20 (Octobre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 20 (Octobre 2009) . - pp. 9346–9349 Titre : Removal of thiophene from coking benzene over SO42−/Fe2O3 solid acid under mild conditions Type de document : texte imprimé Auteurs : Zhanjiang Kang, Auteur ; Hongzhu Ma, Auteur ; Bo Wang, Auteur Année de publication : 2010 Article en page(s) : pp. 9346–9349 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Thiophene  DesulfurizationSolid  superacid Résumé : Desulfurization of thiophene in coking benzene with n-butanol as an alkylating agent over SO42−/Fe2O3 solid superacid at 353 K and atmospheric pressure was investigated. The acidity of the catalyst was measured by temperature-programmed desorption (TPD) of ammonia, and the result confirms that the SO42−/Fe2O3 catalyst has a high acid strength. The sample after reaction was detected by gas chromatography−mass spectrometry (GC-MS), and the results show that thiophene has been removed completely.
