       Adsorption of H₂ and CO, both as pure gases and as mixtures, was studied on a catalyst of the following composition:  Co 34.2, Cu 4.08, ThO₂ 2.33, Ce₂O₃ 0.24% on kieselguhr.  In mixtures the presence of 1 gas promoted the adsorption of the other, even at temperatures considerably below those where the velocity of reaction becomes perceptible.  The increase of adsorption with H₂ was conspicuous, even at 25°.  The adsorption was measured volumetrically and is tabulated in terms of the volume adsorbed by 9.41 gm. of catalyst from the pure gas from 1:1, 1:2, and 2:1 mixtures of H₂ and CO at temperatures up to 178°.  The logs of the values for the rate of adsorption at constant pressure when plotted against the logs of the corresponding volumes adsorbed, gave straight lines that were parallel for different pressures at a given temperature.  The results suggested u=kP/Vⁿ as the empirical relation between the rate of adsorption, the pressure and the amount of adsorption, where u = rate of adsorption in cc./min., P=pressure, V=volume adsorbed, and n and k are constants.
