Kumar, Auteur ; A. S. Mukasyan, Auteur ; E. E. Wolf, Auteur Année de publication : 2011 Article en page(s) : pp. 11001-11008 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Reforming Oxidation Hydrogen production Combustion Modeling Résumé : A novel method for catalyst preparation using combustion synthesis techniques has been used to prepare Cu/Zn/Zr and Pd-based catalysts for oxidative reforming of methanol. Spatially resolved infrared thermography has been used to follow the temperature-time movement of the combustion front on cellulose paper impregnated with the catalyst precursor solution along with other techniques to follow the systematic evolution of the catalyst particles from the initial reactants mixture. These particles have been characterized by their activity/selectivity for methanol oxidation/hydrogen production, BET area, and dispersion of Pd on the surface. Results obtained show that they are extremely active and selective in the low temperature range. A one-dimensional theoretical model is presented that describe the main parameters involved in the front propagation.
