        Measurements of the rate of desorption of H₂ indicate 3 types of active centers for which energies of activation of desorption are 9, 12, and 16.8 kcal., respectively.  The action of adsorbed H₂ and C on the kinetics of CH₄ adsorption on Ni as published previously (abs. 3441 and 3442) is discussed.
