The combined removals of Hg 0 and NO over zeolite (HZSM-5 was chosen to use) modified by copper (Cu/HZSM-5) catalysts were studied under different simulated flue gas conditions. Compared with HZSM-5, Cu/HZSM-5 showed higher activity and performed a synergetic effect for the Hg 0 and NO removal at 250°C. But the excess of copper could cause destruction of the thin pore walls and blocking...
