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 16O0C to form an intermediate decomposition product. This intermediate decomposition product is then calcined and reduced.
L'invention concerne un procédé de préparation d'un catalyseur supporté contenant du cobalt comprenant de petites cristallites de cobalt dispersées de façon sensiblement homogène. Le procédé comprend le dépôt de nitrate de cobalt sur un support, puis le chauffage du support dans une atmosphère contenant de l'oxygène, sensiblement dépourvue d'eau, à environ 160 °C pour former un produit de décomposition intermédiaire. Ce produit de décomposition intermédiaire est ensuite calciné et réduit.
