Procedure: Aluminum sec-butoxide was prepared in accordance with the process described in U.S. Pat. No. 4,242,271. A 75% mixed solution of this aluminum sec-butoxide in sec-butyl alcohol was hydrolyzed at 85° C. with a mixed solution of sec-butyl alcohol containing 30% of water to obtain an alumina slurry. After the alumina slurry was aged at 125° C. for 3 hours in an electromagnetically stirring autoclave, water was immediately added to the alumina slurry until a solids content was 20%, and the thus-treated alumina slurry was cooled. The pH of the alumina slurry was adjusted with a 3.8% aqueous solution of nitric acid to obtain Alumina Hydrate 6A. Alumina hydrate A obtained by drying colloidal sol of this alumina hydrate was determined by X-ray diffractometry and found to have a pseudoboehmite structure. At this time, the BET specific surface area was 175 m2/g, and the pore volume was 0.65 ml/g. Incidentally, the specific surface area and pore volume were determined by the following respective methods. to obtain an alumina slurry was immediately added to the alumina slurry until a solids content the thus-treated alumina slurry was cooled
