Highly efficient catalysts based on intermetallic compound Ni3Al obtained by self-propagating high temperature synthesis were investigated. Catalytic tests in the course of carbon dioxide based methane reforming were carried out at atmospheric pressure within the temperature range of 600-950 °C. It was established that the activity of intermetallic compounds increases with increasing the nickel content in the system. The methods of SEM, EDX, HRTEM, EDAX, XRD, and DSC proved that exposing high temperature values and severe redox medium in the course of the reaction results in an insignificant destruction of catalysts' initial structure with the formation of carbon deposits with ordered structure and fibrous morphology, which does not prevent the methane-to-synthesis-gas conversion reaction to occur.
