Composition with denitration function, preparation method and denitration method

The invention relates to the technical field of environmental protection and catalysis, and discloses a composition with a denitration function, a preparation method and a denitration method. The composition comprises an organic matter, activated carbon, an organic acid, a calcium-containing inorganic matter and an optional auxiliary agent, wherein the organic matter is selected from at least one of alkane with the carbon atom number larger than 5, olefin with the carbon atom number larger than 5 and low-carbon monohydric alcohol. The denitration method comprises the step of contacting the composition with flue gas. The composition with the denitration function is high in denitration efficiency, and compared with an amino denitration agent, the composition with the denitration function is free of secondary pollution and not prone to volatilization. 本发明涉及环境保护与催化技术领域，公开了一种具有脱硝功能的组合物及制备方法和脱硝方法。所述组合物包括有机物、活性炭、有机酸、含钙的无机物和可选的助剂，所述有机物选自碳原子数大于5的烷烃、碳原子数大于5的烯烃和低碳一元醇中的至少一种。所述脱硝方法包括将所述组合物与烟气接触。本发明的具有脱硝功能的组合物脱硝效率高，与氨基脱硝剂相
