        Adsorptions of H₂, CO, and CO₂ on 2 MeOH catalysts, ZnO and ZnO-Cr₂O₃, were measured at 0° and 100°.  In order to obtain reproducible results, it was necessary to clean the surface of H₂O and CO₂ by preliminary evacuation at 400°.  Both these catalysts had adsorptive capacities considerably greater than those of most metal catalysts.  The adsorption of both H₂ and CO is large at very low pressures and rapidly reaches saturation capacity independently of further pressure increase.  The experiments indicate that the heat of adsorption is of the same order as that on metal catalysts.  The mixed oxide catalyst shows greater adsorptive capacity than the ZnO.  The results are consistent with the known facts concerning MeOH synthesis on these catalysts.
