Kinetic study of methanol synthesis over CuO / ZnO / Al2O3 / V2O3 catalyst deposited on a stainless steel surface / David Perko in Industrial & engineering chemistry research, Vol. 51 N° 2 (Janvier 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 2 (Janvier 2012) . - pp. 710-718 Titre : Kinetic study of methanol synthesis over CuO / ZnO / Al2O3 / V2O3 catalyst deposited on a stainless steel surface Type de document : texte imprimé Auteurs : David Perko, Auteur ; Janez Levec, Auteur Année de publication : 2012 Article en page(s) : pp. 710-718 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Stainless  steel  Catalyst  Kinetics Résumé : A spraying method for coating stainless steel surfaces with a commercial methanol synthesis catalyst was studied for the purpose of making a thin, active, and durable plate catalyst. The catalyst slurry was composed of CuO/ZnO/Al2O3/V2O3 powder dispersed in 2-propanol and was sprayed on a curved stainless steel surface. The coating was found to exhibit good adhesion to the metal surface and to provide a considerable increase in surface area relative to the geometrical area of the metal support surface (up to a factor of 11000). The effects of key method parameters, namely, the size of the catalyst particles in the suspension and the coating thickness, on the efficiency of coating and the morphology and durability of the coating were briefly investigated. The intrinsic kinetics of carbon dioxide and carbon monoxide hydrogenation, as well as the WGS reaction, on the prepared plate catalyst were evaluated and compared to literature data. The reactions were carried out in a continuous stirred-tank reactor (CSTR) system appropriately assembled with a curved plate catalyst in the absence of mass-transfer limitations.
