The present invention relates to stabilized supports stable at temperatures above 800 ~C, and method of preparing such supports, which includes adding a rare earth metal to an aluminum-containing precursor prior to calcining. The present invention can be more specifically seen as a support, process and catalyst wherein the stabilized alumina catalyst support comprises a rare earth aluminate with a molar ratio of aluminum to rare earth metal greater than 5:1 and, optionally, an aluminum oxide. More particularly, the invention relates to the use of catalysts comprising rhodium, ruthenium, iridium, or combinations thereof, loaded onto said stabilized supports for the synthesis gas production via partial oxidation of light hydrocarbons, and further relates to gas-to-liquids conversion processes.
La présente invention concerne des supports stabilisés à des températures stables supérieures à 800 ·C, et un procédé de préparation desdits supports, qui consiste à ajouter un métal des terres rares à un précurseur contenant de l'aluminium avant frittage. La présente invention concerne plus spécifiquement un support, un procédé et un catalyseur, le support de catalyseur d'alumine stabilisé comprenant un aluminate des terres rares présentant un rapport molaire d'aluminium comparé au métal des terres rares supérieur à 5:1 et, éventuellement, un oxyde d'aluminium. Plus particulièrement, l'invention concerne l'utilisation de catalyseurs, notamment de rhodium, de ruthénium, d'iridium, ou de leurs combinaisons, chargés sur lesdits supports stabilisés pour la production de gaz de synthèse via oxydation partielle d'hydrocarbures légers, ainsi que des procédés de conversion de gaz en liquides.
