Influence of pressure on the rate of the water-gas shift reaction over a commercial Fe oxide-Cr oxide catalyst was studied in the pressure range 1-30 atm. at 346° and 404°. The activity of the catalyst approximately doubled as the pressure was raised to 10 atm. and increased only slightly as the pressure was increased further. Plots of catalyst activity versus pressure gave curves similar in shape to Langmuir isotherms.
