Abstract:
The catalytic activity of several samples based on nickel aluminides in methane conversion with carbon dioxide was studied. Nickel aluminides were prepared by the method of self-propagating high-temperature synthesis. The Ni3Al system containing the nickel metal phase exhibited high activity at temperatures above 1073 K. The systems based on Ni2Al3 and NiAl only containing intermetallic compound phases were inactive.
