摘要: The thermal desorption of H/sub 2/, D/sub CO, and CO/sub 2/ from the surface industrial reduced nickel--alumina nickel--alumina--calcium methanation catalysts was studied mass spectrometrically. Hydrogen carbon monoxide adsorbed in two forms, but dioxide only one form. low-temperature form hydrogen is mainly molecular high-temperature atomic. nickel nonhomogeneous for each adsorption. An intermediate compound composition HCOH detected during hydrogenation intermediates 2/C(OH)/sub were that 2/. mechanism CO discussed.
