    摘要: A process for the preparation of a very hard catalyst carrier from a mixture of aluminum oxides which in addition to .alpha.-Al.sub.2 O.sub.3 contains other modifications, preferably .gamma.-Al.sub.2 O.sub.3. The .alpha.-Al.sub.2 O.sub.3 is first pretreated with an acid, base and/or metal salt solution and is then mixed with the other aluminum oxides or their intermediates.
