        Static volumetric method for measuring adsorption of gases by solids at elevated pressures was developed, and the adsorption of H₂ on a Fe-K₂O-Al₂O₃-TiO₂ catalyst at temp. 50°-350° and pressure 15-50 atm. was studied.  2 distinct types of activated adsorption of H₂ were found, 1 with a maximum at about 150°, the other with a maximum at about 300°.  The results indicate the superposition of adsorption on the chemisorption of the H₂.
