Larger amounts of alkalis, alkali earth metals and sulfides in flue gas from glass furnace were easier to deactivate selective catalytic reduction (SCR) catalyst compared to the flue gases from other stationary sources. Catalyst regeneration has been an emerging in glass furnace. Regeneration of the deactivated TiO2-ZrO2-CeO2/Al2TiO5-TiO2-SiO2 (ATS) complex phase ceramics catalysts used for NH3-SCR of NOx in glass furnace was studied in this work. Effects of regeneration and thermal regeneration with SO2 on cataytic performance wre comparatively investigated. Washing time directly affected catalyst regeneration efficiency and catalyst life. The regenerated TiO2-ZrO2-CeO2/ATS catalyst regained more than 90% NO conversion after being washed with 10 wt.% H2SO4 for 30 min.
