Abstract
In CO2 reforming of methane catalytic systems based on Ni3Al with various nickel and aluminum content were investigated. Catalysts were obtained using the self-propagating high-temperature synthesis. The XRD technique was used to investigate the phase content of the studied systems. It was demonstrated that the catalytic activity of the samples grows upon an increase in the nickel content of the system. By means of scanning electron microscopy, elemental analysis, and differential thermal analysis, it was demonstrated that these catalytic systems undergo structural changes and carbonize negligibly with remaining catalytic activity in time.
