NOVELTY - Preparing denitration agent involves adding liquid precursor into graphene oxide and uniformly mixed, then adding limestone powder, nano-scale calcium oxide, nano-scale magnesium oxide, titanium dioxide and sodium carbonate, carrying out the working procedures of dipping, reduced pressure distillation and sintering to obtain a denitrifier carrier. The denitration agent and ammonia water are added, loaded the denitration agent and the ammonia water on a denitration agent carrier through dipping and drying processes, and granulated. USE - Method for preparing denitration agent for waste gas treatment. ADVANTAGE - The denitration agent has high efficiency, cheap and easy raw materials, simple to process, cost-effective, high thermal stability and adsorption efficiency reaches 95% and emission standard. The treatment process is simple, and the high-temperature waste gas adsorption device has wide application prospects.
