Process for increasing carbon monoxide hydrogenation activity of catalysts via low temperature oxidation with water, steam or mixture thereof

Abstract From the Canadian patent

A process for increasing the hydrogenation activity particularly the carbon , monoxide hydrogenation activity of a catalyst or catalyst precursor comprised of a particulate solides support component and a catalytic metal or metals , component preferably cobalt; cobalt alone or cobalt and an additional metal or metals added to promote or modify the reaction produced by the cobalt. Treatment of the catalyst, or catalyst precursor is conducted at low temperature ranging from ambient to about 275~C sufficient to form on the surface of a catalyst precursor, e.g. a cobalt catalyst precursor a cobalt , metal hydroxide, low valence cobalt metal oxide or mixture of cobalt metal , hydroxide and …
