The adsorption of CO on Ni at 300/sup 0/C is dissociative, resulting in disproportionation to CO/sub 2/ and a Ni-C species. The surface carbon species formed from CO is readily hydrogenated at 300/sup 0/C to methane. At room temperature, the CO sorption on Ni is nondissociative, and the adsorbed CO is inert to H/sub 2/. In contrast, the Ni-C species formed from CO at 200 to 300/sup 0/C reacts with H/sub 2/, even at room temperature, forming C/sub 1/ to C/sub 4/ paraffins. Co and Ru metals show behavior very similar to that of Ni. In contrast to Ni, Co, and Ru metals, the adsorption of Co on Pd at 300/sup 0/C is nondissociative, and the chemisorbed CO is less reactive to H/sub 2/ than the M-C species formed on Ni, Co, or Ru.
