Khan, Auteur ; Arvind Rajendran, Auteur ; Zhiping Lai, Auteur Année de publication : 2011 Article en page(s) : pp. 12423-12428 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Diffusion  Reactor Résumé : Core—shell micromembrane reactors are a novel class of materials where a catalyst and a shape-selective membrane are synergistically housed in a single particle. In this work, we report the synthesis of micrometer -sized core-shell particles containing a catalyst core and a thin permselective zeolite shell and their application as a micromembrane reactor for the selective hydrogenation of the 1-hexene and 3,3-dimethyl-1-butene isomers. The bare catalyst, which is made from porous silica loaded with catalytically active nickel, showed no reactant selectivity between hexene isomers, but the core-shell particles showed high selectivities up to 300 for a 1-hexene conversion of 90%.
