Experimental Study for Elemental Mercury Removal Using 5% Co-Ti-Pillared Clays Catalysts

摘要

Experimental study on elemental mercury removal by 5% Co-Ti-Pillared clays catalysts was conducted in simulated flue gas with the addition of HCl. Effects of experimental conditions and gas components on the removal efficiency of zero-valent mercury (Hg0) catalytic were investigated. Results show that the addition of HCl in flue gas would significantly promote Hg0 removal efficiency. NH3/NO in flue gas would inhibit the activity of catalyst. The adsorption of water vapor and Hg0 would change into a competitive mechanism form which would influence Hg0 catalytic removal efficiency.
