    摘要: A method is described for lowering the nitrate content in a cobalt catalyst precursor formed by impregnating a catalyst support with cobalt nitrate, comprising calcining the impregnated support in air to effect partial denitrification and subsequently heating the calcined impregnated support to a temperature below 250° C. in the presence of a gas mixture comprising 0.1-10% hydrogen by volume in an inert gas.
