NOx Reduction by In Situ Catalytic Reduction in the Combustion Process of Coke

Abstract:

A new method, NOx reduction by in-situ catalytic effects of additives loaded in coke, was proposed. A series of coke samples with different loading amounts of CaCl₂, Ce(SO₄)₂ and La₂(SO₄)₃ were prepared by using the impregnation method, the rules of NOx and CO emissions in the combustion were investigated. The results show that CaCl₂, Ce(SO₄)₂ and La₂(SO₄)₃ play in-situ catalytic effects on the NOx reduction reactions. When the loading of CaCl₂ is 4.0%, the amount of NOx emission is reduced by 13.9%. When the loading of Ce(SO₄)₂is 4.0%, the amount of NOx emission decreases by 17.2%. When the loading of La₂(SO₄)₃ is 4.0%, the amount of NOx emission decreases by 8.7%. Ce(SO₄)₂ possesses the combustion-supporting effect. As 4.0% Ce(SO₄)₂ in coke, the CO emission is reduced by 26%, which improves the combustion efficiency of coke.
