Activation of Saturated Hydrocarbons on Solid Catalysts

Catalytic Transformation of Methane into Aromatics Under Non-OxiDATiVE Conditions 

The intensities of signals at —14, 0, and 30 ppm increased with increasing molybdenum loading (152). A series of Al MAS NMR spectra indicated that, with increasing amounts of ammonium heptamolybdate, a dealumination occurred as a 

Methane dehydroaromatization on zeolites Mo/HZSM-5 was also investigated by solid-state MAS NMR spectroscopy 162. Both variation of the state of the transition metal component and products (such as ethane, benzene, and ethylene) adsorbed in zeolite were observed after reaction at high temperature (900-1000 K). Molybdenum carbide species, dispersed on the external surface or in the internal channels of the zeolite catalysts, had formed during the reaction 162.
