Abstract

Abstract: Gaseous pollutants emitted from coal combustion are very harmful to environment and human health.As a green oxidant,H₂O₂ has thus received much attention in removing pollutants in coal-fired flue gas in recent years.A review of H₂O₂ oxidation technology to remove SO₂,NO and Hg⁰ in flue gas both at home and abroad is briefly summarized,including H₂O₂ oxidation coupling technique,Fenton oxidation and Fenton-like oxidation. The important influencing parameters,removal efficiency and mechanism are discussed.Meanwhile,new techniques such as photocatalysis-Fenton,H₂O₂ gasification and heterogeneous catalytic oxidation in purifying coal-fired fuel gas are introduced.The results provide reference for achieving greater purification efficiency in the field.

Key words: fuel gas purification, H₂O₂, Fenton, Fenton-like
