摘要
Methane dehydroaromatization on Mo/HZSM-5 and W/HZSM-5 catalysts was studied by solid state C-13 NMR spectroscopy, both variation of the state of transition metal component and products such as ethane, benzene, ethene adsorbed on or in zeolite were observed after high temperature (900-1000 K) reaction.
