A series of carbon supported nickel catalysts of various metal dispersion was characterized by temperature-programmed reduction and adsorption of hydrogen, carbon monoxide and oxygen. The examinations showed that some carbon species appear on nickel surface in the course of routine purging of the catalysts from hydrogen. The species weaken the adsorption of hydrogen but does not affect the adsorption of carbon monoxide. Dispersion of nickel determined from hydrogen, carbon monoxide and oxygen adsorption was the same, which indicates the usefulness of these adsorbates for characterizing of carbon supported nickel catalysts.
