Abstract:
A process for increasing the hydrogenation activity of a cobalt, catalyst, or for forming an oxidized cobalt catalyst precursor which, upon reduction can be converted to a cobalt catalyst for conducting carbon monoxide hydrogenation reactons, consisting essentially of:contacting an oxidant, in the presence of water, with said catalyst or catalyst precursor characterized as a particulate solids composite consisting essentially of a support component, and a cobalt component at least a portion of which is present as metallic cobalt, while maintaining the oxidant and water at a temperature ranging from about 0Â° C. to 200Â° C. sufficient upon reduction, to increase the hydrogenation activity of the cobalt catalyst, or oxidize at least a portion of said cobalt metal component upon the surface of the particulate solids support of the catalyst precursor as a cobalt cationic or oxy-anionic species such that, on seduction, the carbon monoxide hydrogenation activity of the catalyst is increased.
