The present invention relates to thermally stable supports and catalysts for use in high temperature operation, and methods of preparing such supports and catalysts, 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 thermally stable support comprises two rare earth aluminates of different molar ratios of aluminum to rare earth metal, and optionally, alumina and/or a rare earth oxide. More particularly, the invention relates to the use of noble metal catalysts comprising the thermally stable support for synthesis gas production via partial oxidation of light hydrocarbon (e.g., methane) with minimal deactivation over long-term operations and further relates to gas-to-liquids conversion processes.

La présente invention concerne des supports et des catalyseurs thermostables destinés à être utilisés lors d'un fonctionnement à haute température, ainsi que des procédés de préparation desdits supports et catalyseurs qui consistent à ajouter un métal des terres rares à un précurseur contenant de l'aluminium avant calcination. La présente invention concerne plus spécifiquement un support, un procédé et un catalyseur, le support thermostable comprenant deux aluminates des terres rares présentant des rapports molaires différents d'aluminium comparé au métal des terres rares, et éventuellement, de l'aluminium et/ou un oxyde des terres rares. Plus particulièrement, l'invention concerne l'utilisation de catalyseurs à base de métaux nobles comprenant le support thermostable pour la production de gaz de synthèse via oxydation partielle d'hydrocarbures légers (par ex., du méthane) avec désactivation minimale lors de fonctionnements de longue durée et concerne également des procédés de conversion de gaz en liquides.
