Reforming titanium oxide particles and method for producing the same, as well as exhaust gas treatment catalyst for using this reformed titanium oxide particles

摘要

PROBLEM TO BE SOLVED: To provide a modified titanium oxide particle suitable for an exhaust gas treating catalyst or the like for treating a waste gas discharged from a combustion furnace and containing NOx and SOx by using a reducing agent such as ammonia, to provide its manufacturing method and to provide the exhaust gas treating catalyst having a high denitrification activity and also a low SO₂ oxidation rate and excellent durability.;SOLUTION: The modified titanium oxide particle wherein the surface of titanium oxide particles containing silica and/or zirconia is covered with peroxotitanic acid, its manufacturing method and the exhaust gas treating catalyst using the modified titanium oxide particle are provided.;COPYRIGHT: (C)2008,JPO&INPIT
