Adsorptive removal of dimethyl disulfide in olefin rich C4 with ion-exchanged zeolites / Jieun Lee in Industrial & engineering chemistry research, Vol. 50 N° 10 (Mai 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 10 (Mai 2011) . - pp. 6382-6390 Titre : Adsorptive removal of dimethyl disulfide in olefin rich C4 with ion-exchanged zeolites Type de document : texte imprimé Auteurs : Jieun Lee, Auteur ; Hee Tae Beum, Auteur ; Chang Hyun Ko, Auteur Année de publication : 2011 Article en page(s) : pp. 6382-6390 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Zeolite Résumé : The purpose of this study is to investigate the removal of dimethyl disulfide (DMDS) in the olefin rich Fluid Catalytic Cracking (FCC) C4 hydrocarbon mixture with the ion-exchanged β-zeolite. Effects of Si/Al ratio, metal cations, and the ion exchange level on the removal efficiency have been accessed by performing the breakthrough experiment with a model C4 mixture of 20 ppm DMDS in 40% n-Butane/60% 1-Butene. The metal ions used for the preparation of ion exchanged zeolite are Ag(I), Cu(II), Ni(II), Fe(III), and Cu(I). The adsorption characteristics of 1-Butene and DMDS on the adsorbent have been studied through the temperature programmed desorption (TPD).
