The paper gives results of a study of the absorption of elemental mercury at 125 C by a sulfuric-acid (H2S04, 50% w/w solution)-treated carbon for the removal of mercury from flue gas. The pore structure of the sample was characterized by nitrogen (N2) at -196 C and the t-plot method analysis. Thermogravimetric analysis (TGA) was used to examine the thermal behaviors of the treated sample. Study results show that the H2S04-treated carbon has a very high elemental mercury capture capacity (27 mg/g) via a physisorption mechanism. The pore volume and surface area of the treated carbon were drastically reduced due to absorption of the H2S04 in the micropores of the carbon, resulting in a narrower microporosity.
