<p>A process for the preparation of agglomerates of aluminium oxide is disclosed. The process comprises contacting a hydrous aluminium oxide gel with an organic liquid which is essentially immiscible with water. The organic liquid is utilized in an amount such that the weight ratio of said liquid to water, as contained in the hydrous gel, lies within Region II of a plot of said ratio versus the pore volume of aluminium oxide obtained after being dried and calcined. Subsequent to the gel being contacted with the organic liquid, the gel is subjected to agglomeration conditions. Region II of the referenced plot is a region in which the slope of the curve plotting the ratio of organic liquid to water versus the pore volume, as discussed above, has a value equal to or greater than about 4.0.
