摘要：

By using C-13 solid-state NMR and GC-MS, the analysis of the C-13-label transfer from methane-C-13 into the products of methane and propane co-aromatization on Zn/H-BEA zeolite at 823-873 K has been performed. A high degree involvement of C-13-Carbon atoms of methane into aromatic products (benzene, toluene, xylenes) has been demonstrated. The main pathway of methane conversion into aromatics has been determined to consist in the methylation of aromatics, which is produced exclusively from propane, by methane. The methoxy species formed by the dissociative adsorption of methane on ZnO species of the zeolite is responsible for the methylation. (C) 2008 Elsevier B.V. All rights reserved.
