Abstract
Catalytic systems based on the Ni3Al intermetallic compound and modified with chromium and tungsten were studied in carbon dioxide reforming of methane. The catalysts were prepared by the self-propagating high-temperature synthesis method. The phase composition of the catalytic systems was determined by X-ray diffraction. The catalytic activity of the samples increased as the concentration of dopants decreased and was maximum at 2 wt % Cr and W. Scanning electron microscopy studies showed that the catalytic system underwent substantial structural changes responsible for catalytic activity loss with time.
