- Abstract
The molybdenum precursor effect on the physicochemical properties of the Мо/ZSM-5 catalyst and on its catalytic properties in nonoxidative methane conversion into aromatic hydrocarbons has been investigated. The textural characteristics of molybdenum catalysts have been determined by low-temperature nitrogen adsorption, and their acidity has been measured by temperature-programmed ammonia desorption. The microstructure and composition of Mo/ZSM-5 samples have been determined by high-resolution transmission electron microscopy and energy-dispersive X-ray spectroscopy. The activity and on-stream stability of the Мо-containing zeolite catalyst in the nonoxidative conversion of methane depend on the type of molybdenum compound that was used in catalyst preparation.
