This high efficient carbon with powder size aims to reduce the content of hydrargyrum vapor discharged from fire coal power plant and fire furnace. It achieves the chemical and physical treatment to the hydrargyrum among the smoke gas by attaching bromine into the developed micropore organization. The hydrargyrum adsorption capacity of Huahui" Demercuration Carbon can get more than 0.3mg/g.
