燃煤锅炉烟气中NH3-SCR钒基催化剂宽温脱硝的研究进展
Progress of wide-temperature denitrification over vanadium-based catalysts for NH3-SCR in flue gas from coal-fired boilers
摘要
Abstract
Nitrogen oxides(NOx)are among the primary atmospheric pollutants,posing a significant threat to human health and the environment.The NH3-SCR technology is a crucial method for reducing nitrogen oxides from fixed sources and has been extensively implemented in the coal-fired power generation sector.Vanadium(V)-based catalysts have garnered considerable attention due to their superior denitrification activity.However,the traditional V-based catalysts can no longer meet the industry requirements because of the profound transformations in the energy industry.Consequently,it has become imperative to modify the V-based catalysts to operate effectively across a broad temperature range and enhance their resistance to poisoning.This review focuses on the recent advancements in the wide-temperature denitrification capabilities and poisoning resistance of the V-based catalysts in the coal-fired power generation industry.To enhance the low-temperature performance,the temperature window should be effectively expanded by modifying the active components and carriers,and optimizing the catalyst structures.Furthermore,an in-depth analysis of deactivation factors is presented,including the poisoning mechanisms induced by ammonium bisulfate(ABS),H2O,alkali/alkaline earth metals,phosphorus,and halogens,as well as the corresponding strategies to improve the anti-poisoning performance.Finally,the research direction of the V-based catalyst in the energy transformation of power generation industry is put forward.关键词
