Abstract
An improved method for increasing alumina pore volumes said alumina being produced by the hydrolysis of aluminum alkoxides, the improvement comprising diluting the aluminum alkoxide, prior to entering the hydrolysis reactor, with an alkanol containing from 2 to 8 carbon atoms and injecting the dilute solution into the reactor at high velocities.
