STABILIZATION OF TRANSITION ALUMINA

摘要

The present invention relates to a process for the production of a precursor material for use in the preparation of a stabilized alumina catalyst support material, which process comprises the steps of: (a) providing a mixture comprising aluminium and barium containing compounds; and (b) heating the mixture under conditions to form particles of boehmite at least partially coated with a layer comprising barium and/or a compound of barium.
