This paper focused on the influence of flue gas component change on elemental mercury (Hg-0) adsorption by powder activated carbon from apricot's shell and discussed the Hg-0 adsorption characteristics and mechanism of activated carbon. Experimental results showed that activated carbon from apricot's shell had no Hg-0 adsorption ability in the non-oxidizing atmosphere, such as N-2, N-2 + CO2 etc. Though the influence on homogeneous oxidation reaction of Hg-0 was limited, NO2 was the key factor on heterogeneous catalytic oxidation reaction of Hg-0 on the surface of activated carbon. It was easy to form NO2 by reaction between the NO and O-2. It could also enhance the Hg-0 adsorption ability of activated carbon through preloading NO2 on the surface. Based on these experimental results, it finely proved that Hg-0 adsorption by activated carbon was a heterogeneous catalytic oxidation reaction.
