Sulfur Poisoning and Regeneration of SCR Catalyst Based on V₂O₅/TiO₂

Abstract:

The deactivation and regeneration of SCR catalyst have caught attention in the coal-fired power plant. Sulfur poisoning was one reason of the SCR catalyst deactivation. The V₂O₅/TiO₂ catalyst was prepared by sol-gel method. The SO₂ poisoning of V₂O₅/TiO₂ catalyst was investigated. The catalytic activity by thermal regeneration and thermal reduction methods were compared. The results showed that thermal regeneration or thermal reduction could recover the catalytic activity effectively. The best effect was obtained with the thermal reduction by 5% NH₃ concentration.
