Water-soluble biomass SNCR (selective non-catalytic reduction) denitration agent as well as preparation method and application thereof

The invention discloses a water-soluble biomass SNCR (selective non-catalytic reduction) denitration agent as well as a preparation method and application thereof, and the method comprises the following steps: adding 5-10 parts of concentrated sulfuric acid into 5-10 parts of a biomass material for sulfonation reaction; filtering to remove biomass residues after sulfonation reaction to obtain water-soluble biomass sulfonation liquid; adding 2-5 parts of organic acid into the water-soluble biomass sulfonated liquid, and uniformly mixing to obtain a mixed solution; 28-65 parts of water is added into the mixed solution for dilution, and the water-soluble biomass SNCR denitration agent is obtained. The process is high in safety, safe and controllable; the method is simple to operate and easy to master, can achieve the effect of quick and simple construction, can greatly reduce the process cost, and does not cause secondary pollution to the environment. 本发明公开了一种水溶性生物质SNCR脱硝剂及其制备方法、应用，所述方法包括以下步骤：向生物质材料5-10份，加入5-10份
