Abstract

Abstract:

Series TZC/ATS catalysts and the tungsten-added samples, with Ti_0.8Zr_0.2Ce_0.2O_2.4 (TZC for short) as active component and Al₂O₃-TiO₂-SiO₂ (ATS for short) as catalyst carrier, were prepared by extrusion method. Effects of tungsten incorporation on catalytic performance and tolerance towards K₂O and CaO poisoning of TZC/ATS for deNO_x by NH₃ selective catalytic reduction (NH₃-SCR) were mainly studied, and anti K₂O and CaO poisoning abilities between the TZCW_0.4/ATS and the V₂O₅(WO₃)/TiO₂ were comparatively analyzed. Moreover, the specific surface, solid-phase structure, morphology and surface acidity of the catalysts were characterized by techniques of N₂-BET, XRD, SEM and NH₃-TPD, respectively. Results showed that the TZCW_0.4/ATS catalyst exhibited the highest catalytic activity and the best stability for deNO_x by NH₃-SCR when the Ti/Zr/Ce/W molar ratio of the active component was 4:1:1:0.4. Furthermore, tungsten incorporation greatly enhanced the anti K₂O and CaO poisoning abilities of the TZCW_0.4/ATS catalyst, and these anti-poisoning abilities of the TZCW_0.4/ATS were much stronger than those of the V₂O₅(WO₃)/TiO₂. The promotional effect on catalytic deNO_x performance was caused by increased specific surface area and enhanced surface acidity of the TZCW_0.4/ATS catalyst after tungsten incorporation.

Key words: Ti0.8Zr0.2Ce0.2O2.4/Al2O3-TiO2-SiO2 catalyst, tungsten incorporation, cement flue gas deNOx, anti K2O poisoning, anti CaO poisoning
