Abstract

A method is provided for preparing a supported cobalt-containing catalyst having substantially homogenously dispersed, small cobalt crystallites. The method comprises depositing cobalt nitrate on a support and then heating the support in an oxygen-containing, substantially water-free atmosphere to about 160° C. to form an intermediate decomposition product. This intermediate decomposition product is then calcined and reduced.
