Zusammenfassung: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 aping the precursor mixture at an elevated temperature under agitation with an effective consumptive power of greater than 1 kW/m3.
