Experimental Study on Titanium Based Photocatalyst and Its Catalytic Oxidation on Flue Gas mercury

摘要

This paper mainly studied the effects of different iron-doped volume on photo-catalytic oxidation of TiO_2 for mercury removal. Through the photocatalytic oxidation system, we evaluated the elemental mercury removal performance of TiO_2 with iron-doped mass ratio of 0.5%, 1%, 2% and 3%. While the iron-doped mass ratio were 0.5%, 1%, 2% and 3%, the elemental mercury removal efficiency were 70.83%, 52.89%, 72.32% and 62.39% respectively, the removal efficiency increased firstly, then declined, and 2% iron-doped was the most appropriate.
