Investigation of the state of hydrogen in a nickel-chromium catalyst by the method of thermodesorption

The interaction of hydrogen with an industrial reduced nickel-chromium catalyst was investigated by the method of thermodesorption in the interval 30–300°C.
There are four forms of chemisorbed hydrogen on the surface of the catalyst; the nature of the surface inhomogeneity of the catalyst was established, and the activation energies of desorption were determined for all four forms of adsorption.
The influence of diffusion on the behavior of thermodesorbed hydrogen was detected.
