Leybo D.V, Chuprunov K.O, Kuznetsov D.V, Levina V.V
The influence of initial components ratio on the phase formation features in Ni-Mo-N system is studied in this work. Analysis was performed by X-Ray diffraction, low-temperature nitrogen adsorption, thermogravimetry, Fourier transform infrared spectroscopy methods in this study. It was shown that the formation of the single phase specimen occurs when Ni:Mo ratio equals 2:3. The influence of metallic and intermetallic phases formation on specific surface area of the powder is revealed. The study of catalytic activity and stability of nitride catalyst in methanation reaction was performed. It was shown that they key product of the reaction is methane, which is confirmed by the IR transmission spectra. After 360 minutes of the reaction there are peaks of carbon monoxide, which is weighty confirmation of its presence in the product mixture. The reverse water-gas shift reaction may promote the increase of CO concentration.
