<P>PROBLEM TO BE SOLVED: To provide an aluminum oxide-titanium oxide mixture molded burned object exhibiting a large pore volume and a large average pore radius. <P>SOLUTION: The aluminum oxide-titanium oxide mixture molded burned object is obtained by mixing aluminum oxide powder and titanium oxide powder with a water-soluble polymer of ≥5 parts by mass per 100 parts by mass of the total amount of the aluminum oxide powder and titanium oxide powder, and then molding and burning the resulting mixture. The water soluble polymer is, for example, polyethylene glycol, polyvinyl alcohol, acrylamide, cellulose ether or the like. The mass ratio of the use amounts of the aluminum oxide powder and the titanium oxide powder is 20:80 to 80-20. A catalyst for oxidation of hydrogen chloride is obtained by supporting ruthenium oxide on the obtained molded burned object, and chlorine can be produced by the reaction of hydrogen chloride and oxygen in the presence of the catalyst. <P>COPYRIGHT: (C)2008,JPO&INPIT |
