负载金属催化剂的褐煤活性半焦脱除烟气中NO性能及机理
NO removal with carbon catalyzed by activated-char-supported metals during flue gas cleaning
摘要
Abstract
In this paper,the removal of NO from flue gas by lignite activated char loaded metal catalyst was studied,and the reaction mechanism was discussed. Denitrification experiments were carried out using the homemade denitrification agent in a fixed bed reactor. The surface morphology,element distribution and metal phase form of the denitrification agent before and after the reaction were analyzed by using Fourier transform infrared(FTIR)and X ray diffraction(XRD). The results show that copper has better denitrification performance than other metals and adding iron in copper based catalyst activated char improved its denitrification performance. The denitrification rate reached 8.70g/(100g activated char). During the denitrification process,the catalysts gradually deactivated due to the oxidation of the active metal phases,while the composite metal oxide copper ferrite was decomposed into activated metal with higher activity phase,which improved the denitrification performance.关键词
