Abstract

Co/Al2O3 catalysts prepared by changing pH coprecipitation with Co loadings in the 8.7–36 wt.% range were analyzed by TSA, TPV, pore structure, XRD as well as CO, H2, O2 adsorption and CO hydrogenation. High O2 uptake and reducibility coupled with low dispersion and constant MSA above 17 wt.% Co indicate large crystallites that are less exposed to H2. CO hydrogenation per Co site decreases with increasing dispersion or decreasing metal loading.
