Preparation and characterization of alumina - based microreactors for application in methyl chloride synthesis / Sabrina A. Schmidt in Industrial & engineering chemistry research, Vol. 51 N° 12 (Mars 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 12 (Mars 2012) . - pp. 4545–4555 Titre : Preparation and characterization of alumina - based microreactors for application in methyl chloride synthesis Type de document : texte imprimé Auteurs : Sabrina A. Schmidt, Auteur ; Narendra Kumar, Auteur ; Biao Zhang, Auteur Année de publication : 2012 Article en page(s) : pp. 4545–4555 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Microreactors  Alumina  catalyst Résumé : Microreactor platelets were coated with an alumina catalyst for use in methyl chloride synthesis. The coating was extensively characterized regarding its uniformity, thickness, and stability by using SEM, confocal microscopy, and EDX. The influence of the platelet pretreatment on the coating stability was investigated with different stability tests. A straightforward method to obtain a stable and uniform coating was developed, and the coated platelets were used for the synthesis of methyl chloride. The performance of the microreactor was compared with a tubular fixed bed reactor. The results obtained with both reactors were comparable, but the microreactor allows a rapid catalytic screening with a low consumption of chemicals.
