Metal-support interactions: their effects upon adsorption, electronic, and activity/selectivity properties of cobalt in CO hydrogenation. Annual progress report, April 1, 1982-March 31, 1983

OSTI ID:6031870
During the past year, measurements of dispersion, extent of reduction, H/sub 2/ and CO adsorption stoichiometries, CO hydrogenation activity and selectivity, and H/sub 2/ adsorption/desorption kinetics were conducted on 18 catalysts. Hydrogen adsorption was found to be highly activated and quite reversible; the adsorption stoichiometry corresponds to one hydrogen atom per surface cobalt atom. CO adsorption stoichiometries on the other hand vary considerably with support, dispersion, and preparation. Binding energies and adsorption states for H/sub 2/ on cobalt vary with support. Activity and selectivity in CO hydrogenation on cobalt vary with support, dispersion, and preparation. The specific activity and selectivity for heavier hydrocarbons decrease with increasing dispersion.
