摘要： PROBLEM TO BE SOLVED: To provide a catalyst carrier having improved characteristics, particularly high performance and a low wear value.SOLUTION: There is provided an amorphous catalyst carrier which comprises at least: a first oxide selected from the group consisting of silica, germanium oxide, titanium oxide, zirconium oxide or a mixture thereof, preferably a silica gel bead or diatomaceous earth; a Group-III metal oxide; and anions in an amount of 10 mass% or less of the catalyst carrier, wherein the Group-III metal oxide is incorporated into a first oxide structure at a molecule level. The catalyst carrier is prepared by the steps of: (a) mixing the first oxide with an anhydrous source of the Group-III metal oxide and water at a pH of 11 or more to form a suspension; (b) washing the catalyst carrier with water; (c) separating the catalyst carrier from the water; and (d) optionally and selectively drying the catalyst carrier and/or calcining the catalyst carrier. A catalyst based on such a carrier has improved catalytic properties.
