| 英文摘要 | The reduction of NO by Shenmu coal char was studied at 450, and the relationship between the influencing factors of coal char denitrification and its surface carbon-oxygen functional groups was explored by Raman, FT-IR, XPS and other analytical methods. Combining the results of isothermal experiments and characterizations, close connection between influencing factors and carbon-oxygen complexes was revealed. The effect of coal char preparation temperature, oxygen concentration in flue gas as well as influence of metallic elements could be in connection with carbon-oxygen complexes on coal char surface. More specifically, lowering pyrolysis temperature, increasing oxygen concentration, and loading metals were all conducive to the retention and formation of thermally stable C-O species on coal char surface. Strong linear relationship was discovered via XPS method between thermally stable C-O species and experimental evaluation indexes (R2>0.96). Carbon-oxygen complexes, especially thermally stable C-O compounds, played a key character in NO reduction by coal char. 漏 2022, Editorial Board of CIESC Journal. All right reserved. |
