Özet
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, H-2, O-2 adsorption and CO hydrogenation. High O-2 uptake and reducibility coupled with low dispersion and constant MSA above 17 wt.% Co indicate large crystallites that are less exposed to H-2. CO hydrogenation per Co site decreases with increasing dispersion or decreasing metal loading.
