Being the catalyst which oxidizes the oxidation methodological null ammonia (NH 3 ) of the metal mercury which uses the oxidation

摘要

PROBLEM TO BE SOLVED: To provide a catalyst having high Hg oxidation activity while keeping high denitration activity and low oxidizability of SO₂ in high-temperature exhaust gas containing sulfur dioxide (SO₂) and ammonia (NH₃) and to provide a method for oxidizing metal mercury by using the catalyst.;SOLUTION: The catalyst for oxidizing metal mercury in exhaust gas containing sulfur dioxide (SO₂) and ammonia (NH₃) mainly consists of titanium (Ti), molybdenum (Mo) or tungsten (W), and vanadium (V), and contains iridium (Ir).;COPYRIGHT: (C)2010,JPO&INPIT
