Abstract

The water-gas shift (WGS) activity of bimetallic Pt-Ni/$Al_2O_3$ catalysts was investigated in the temperature range 200-450 $^{circ}C$ using an idealized feed composition consisting of 3% CO and 6%-10% $H_2O$. The effects of the Ni content, space velocity, and $H_2O$/CO ratio on the catalytic performance of the catalysts were studied. An increase in the Ni content and $H_2O$/CO ratio shifted the carbon monoxide conversion– temperature curve toward lower reaction temperatures. No detectable methane formation was observed in the catalytic reaction tests. The results indicate that Pt-Ni/$Al_2O_3$ catalysts are highly selective and active for water-gas shift reactions under idealized conditions.
