Abstract: front page image
(EN)A method of manufacturing a cobalt catalyst is described, which comprises the steps of forming an aqueous solution of a cobalt amine complex, oxidising said solution such that the concentration of Co(I11) in the oxidised solution is greater than the concentration of Co(III) in the un- oxidized solution, and then decomposing the cobalt amine complex by heating the solution to a temperature between 80 and 110 °C for sufficient time to allow an insoluble cobalt compound to precipitate out of the solution. A catalyst intermediate is also described which comprises a cobalt compound, comprising a Co(II)/Co(III) hydrotalcite phase and a Co3O4 cobalt spine) phase, wherein the ratio of cobalt hydrotalcite phase : cobalt spine) phase is less than 0.6:1, said cobalt hydrotalcite phase and said cobalt spine) phase being measured by X-ray diffractometry.
(FR)La présente invention se rapporte à un procédé de fabrication d'un catalyseur au cobalt, qui comprend les étapes consistant à former une solution aqueuse d'un complexe cobalt-amine, à oxyder ladite solution de sorte que la concentration de Co(III) dans la solution oxydée soit supérieure à la concentration de Co(III) dans la solution non oxydée, puis à décomposer le complexe cobalt-amine par chauffage de la solution jusqu'à une température comprise entre 80 et 110 °C pendant un laps de temps suffisant pour permettre au composé de cobalt insoluble de précipiter dans la solution. L'invention se rapporte également à un intermédiaire catalyseur qui comporte un composé de cobalt contenant une phase hydrotalcite Co(II)/Co(III) et une phase de spinelle cobalt Co3O4, composé dans lequel le rapport de la phase hydrotalcite de cobalt à la phase de spinelle cobalt est inférieure à 0,6:1, ladite phase hydrotalcite de cobalt et ladite phase de spinelle cobalt étant mesurées par diffractométrie de rayons X.
