Ni-Mo carbide catalysts

Then they proposed Ni-Mo carbide catalyst [35] for the low temperature WGS reaction. Among the various catalysts Nio.25Moo.75 catalyst carburized at 873 K was more active than the other catalysts. Usually, Mo carbide catalysts deactivate with time-on-stream. However, Nio.25Moo.75 catalyst carburized at 923 K exhibits stable activity for 300 min of time-on-stream. The Ni contents of 15% and 25% increased the catalytic activity but further Ni content led to a drop in activity. They proposed that the promotion of the WGS reaction activity was due to the formation of Ni-Mo oxycarbide.
