Abstract
A strontium-catalyzed process for preparing boehmite includes combining a strontium material, flash calcined gibbsite, and water to obtain an aqueous suspension; contacting the aqueous suspension with a water-soluble carbonate material; and heating the aqueous suspension to a temperature, and for a time, sufficient to form at least about 5 wt. % of boehmite.
Claims10
A strontium-catalyzed process for preparing boehmite, the process comprising:
- combining a strontium material, flash calcined gibbsite, and water to obtain an aqueous suspension;
- contacting the aqueous suspension with a water soluble carbonate material;
- and
- heating the aqueous suspension to a temperature and for a time sufficient to form at least about 5 wt. % of boehmite based on total weight of the solid;
- wherein the process further comprises removing strontium from the boehmite.
