Multifunctional reactor for the synthesis of dimethylacetal / Carla S. M. Pereira in Industrial & engineering chemistry research, Vol. 47 N°10 (Mai 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°10 (Mai 2008) . - p. 3515–3524 Titre : Multifunctional reactor for the synthesis of dimethylacetal Type de document : texte imprimé Auteurs : Carla S. M. Pereira, Auteur ; Pedro Sa Gomes, Auteur ; Ganesh K. Gandi, Auteur ; Viviana M. T. M. Silva, Auteur Année de publication : 2008 Article en page(s) : p. 3515–3524 Note générale : Bibliogr. p. 3523-3524 Langues : Anglais (eng) Mots-clés : Dimethylacetal;  Simulated  moving  bed  reactor Résumé : The synthesis of dimethylacetal (1,1-dimethoxyethane) was performed in a Simulated Moving Bed Reactor (SMBR) pilot unit LICOSEP 12-26 (Novasep, France) with 12 columns packed with the acid resin Amberlyst-15 wet (Rohm & Haas, France). For the operating conditions used, the performance parameters obtained were as follows:  acetal purity, 91.41%; productivity rate, 5.17 kgacetal/(Ladsorbent day); and desorbent consumption, 7.11 Lmethanol/kgacetal. The effect of the switching time, feed composition, and desorbent flow rate in the performance of the SMBR was studied by means of two mathematical models approaches:  the SMBR model (for the concentration profiles and performance parameters) and the True Moving Bed Reactor (TMBR) model (for the reaction separation regions).
