Reactions of indan over zeolite catalysts / Xiaojing Cheng in Industrial & engineering chemistry research, Vol. 49 N° 20 (Octobre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 20 (Octobre 2010) . - pp. 9759–9763 Titre : Reactions of indan over zeolite catalysts Type de document : texte imprimé Auteurs : Xiaojing Cheng, Auteur ; Guang Xiong, Auteur ; Xinwen Guo, Auteur Année de publication : 2011 Article en page(s) : pp. 9759–9763 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Zeolite  Catalysts Résumé : The reactions of indan were studied over ZSM-5, zeolite β, and mordenite under atmospheric pressure or 3 MPa. Zeolite β shows the best catalytic activity. The main reaction pathways of indan are five-membered ring opening and condensation. The ring-opening reaction of indan follows β scission mechanism. No hydrogenation of indan occurs. When the reaction temperature or the concentration of indan is high, it tends to condensate to form polyaromatics. No effect of aromatics such as benzene or trimethylbenzene was found in the reactions of indan. The existence of indan decreases the conversion of trimethylbenzene because of its preferential adsorption on the catalysts. The amount of indan in the reactant strongly affects the coke amount of the catalyst.
