燃煤耦合可再生燃料电厂抗中毒脱硝催化剂研究进展
Research progress on anti-poisoning of SCR catalysts in flue gas of coal and renewable fuel co-fired power plant
摘要
Abstract
Under the background of Carbon Peak and Carbon Neutralization,the demand for pollution and carbon reduction of coal-fired units is urgent.Co-fired coupled directly with renewable fuel for power generation can not only reduce carbon emissions,but also significantly improve energy utilization level.However,the characteristics of different fuels lead to complex flue gas characteristics after co-combustion,which poses new challenges to SCR catalysts.The article briefly reviews the reaction mechanism of the SCR catalysts,comprehensively elucidates the influence of boiler flue gas after burning co-fired renewable fuels on the catalytic process of SCR catalyst,and discusses in detail the effects of different poisons on the catalytic activity of SCR catalysts.Then,various anti-poisoning strategies for catalyst design are proposed based on different anti-poisoning researches.This paper also expounds the development trend of anti-poisoning catalysts in the future.To achieve low-carbon economic development of thermal power units,it is necessary to clarify the poisoning effect of co-combustion conditions on catalysts,enhance the adaptability of multi-co-combustion scenarios,and improve the yield and quality of industrial products through process improvement.关键词
