摘要：
A catalyst mainly containing silicon oxide and vanadium oxide and having an Si/V atomic ratio within the range from 99.5/0.5 to 85/15 is obtained by gelatinizing a liquid mixture of a colloidal silica and a vanadium compound in advance, then mixing the thus-obtained slurry by heating, and finally drying and/or firing the resulting mixture. As a catalyst for oxidizing mercury metal, this catalyst is brought into contact with an exhaust gas containing mercury metal, thereby oxidizing mercury metal.
