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.

What is claimed is: 1. A high temperature stable catalyst support comprising the following crystalline structures:an alumina phase selected from the group consisting of alpha-alumina, theta-alumina and combinations thereof;a rare earth aluminate of a hexaaluminate or hexaaluminate-like structure comprising at least one rare earth metal and having a high molar ratio of aluminum to rare earth metal between 11:1 and 14:1; anda rare earth aluminate of a perovskite or perovskite-like structure comprising the at least one rare earth metal and having a low molar ratio of aluminum to rare-earth metal of less than 2:1,wherein the catalyst support contains not more than 20% of alpha-alumina, and less than 100 wt % to about 1 wt % of the rare earth aluminate with the high molar ratio of aluminum to rare earth metal.
