Abstract
An object of the present invention is to provide a new method for treating an exhaust gas, which can effectively treat an exhaust gas containing a nitrogen oxide and metal mercury over a long term, and also can be applied to treatment of a large volume of an exhaust gas. As a means of achieving this object, a method according to the present invention for treating an exhaust gas comprises performing a reaction of changing metal mercury into mercury halide in the presence of a halogen compound and treatment of a nitrogen oxide, using a Ti—V-containing catalyst, upon treatment of an exhaust gas containing a nitrogen oxide and metal mercury.
