摘要:
A method for producing high porosity boehmite alumina wherein an aqueous boehmite slurry is mixed with an effective amount of a modifier comprising a hydroxide or oxide of an element of group IIIA-VIA on the Periodic Table of Elements and having a pKsp of greater than 11 to produce a precursor mixture and hydrothermally aging the precursor mixture at an elevated temperature under agitation with an effective consumptive power of greater than 1 kW/m 3 .

摘要:
Magnesium aluminate spinels are made by hydrothermally aging an aqueous slurry of a spinel precursor which can be (a) a mixture of boehmite alumina and a magnesium precursor, (b) an aluminum magnesium oxide or hydroxide, and (c) mixtures thereof. At least one of the aged slurries is dried to remove water and produce at least one dried spinel precursor. The dried spinel precursor is then calcined to produce the magnesium aluminate spinel.
