Adsorption of H2-CO mixtures by Ni foil was determined at low pressure, less than 2 mm. Hg. and over a wide temperature range. At 167° and 329°, H2 and CO are adsorbed in the ratio 3:1, corresponding to CH4 formation, and at 125° and 378°, they are adsorbed in the ratio 2:1, corresponding to higher paraffin formation. The reaction rates also show maximum at these temperatures. Cu adsorbs H2 and to a smaller extent CO only if it contains traces of Th. At 250° and 325°, H2 and CO are adsorbed in the ratio 3:1. Similar experiments with D are described.
