摘要： The present invention relates to a process for the preparation of synthesis gas (i.e., a mixture of carbon monoxide and hydrogen), typically labeled syngas. More particularly, the present invention relates to a regeneration method for a syngas catalyst. Still more particularly, the present invention relates to the regeneration of syngas catalysts using a re-dispersion technique. One embodiment of the re-dispersion technique involves the treatment of a deactivated syngas catalyst with a re-dispersing gas, preferably a carbon monoxide-containing gas such as syngas. If necessary, the catalyst is then exposed to hydrogen for reduction and further re-dispersion.

摘要： This invention relates to methods for making a stabilized transition alumina of enhanced hydrothermal stability, which include the introduction of at least one structural stabilizer; a steaming step before or after the introduction step, wherein steaming is effective in transforming a transition alumina at least partially to boehmite and/or pseudoboehmite; and a calcining step to create a stabilized transition alumina. The combination of the structural stabilizer and the steaming step is believed to impart high hydrothermal stability to the alumina crystal lattice. Particularly preferred structural stabilizers include boron, cobalt, and zirconium. The stabilized transition alumina is useful as a catalyst support for high water partial pressure environments, and is particularly useful for making a catalyst having improved hydrothermal stability. The invention more specifically discloses Fischer-Tropsch catalysts and processes for the production of hydrocarbons from synthesis gas.
