摘要
基于钒钛催化剂是目前选择性催化还原(Selective catalytic reduction,SCR)脱硝技术中应用最为广泛的商业催化剂材料,该催化剂在脱硝的同时也会将部分SO_(2)氧化成SO_(2),进而导致硫酸氢氨生成和沉积,最终对锅炉运行造成不利影响。对氧化机理进行了探讨,并针对机理,基于前人的研究,通过优化催化剂结构和组分来降低SO_(2)的氧化率,进一步提高SCR催化剂的综合性能。开发一种低SO_(2)氧化率的SCR催化剂具有巨大的发展潜力。
Vanadium-titanium catalyst is currently the most widely used commercial catalyst material in Selective catalytic reduction(SCR)denitration technology.And the catalyst also oxidizes part of SO_(2) to SO_(2) during denitration,which in turn leads to the formation and deposition of ammonium hydrogen sulfate,which ultimately adversely affects the operation of the boiler.The oxidation mechanism was discussed,and based on the previous research,the oxidation rate of SO_(2) was reduced by optimizing the catalyst structure and components,and the comprehensive performance of the SCR catalyst was further improved.The development of a low SO_(2) oxidation rate SCR catalyst has great development potential.
