In view of the 500 ℃ high temperature flue gas emitted by coalbed methane (natural gas) power generation, the research team led by Professor Zhao Dongyuan of Fudan University and the team of Associate Professor Fan Jianwei of the School of Environmental Science and Engineering of our school successfully developed a catalyst suitable for high temperature flue gas denitration at 500 ℃, And completed the pilot field experiment, denitrification efficiency more than 95% stability, breaking the technical monopoly of foreign technology in the field of flue gas denitrification. The team used advanced functional nanomaterials preparation technology to prepare the mesoporous zeolitic molecular sieve material as a catalyst carrier by nanometer self-assembly technology, and the active component was assembled into the mesoporous zeolite molecular sieve by using solid state nano-casting and in-situ production technology In the tunnel, a denitrification catalyst was prepared and a denitration catalyst suitable for generating high temperature flue gas (500 ° C) from coalbed methane was developed. Using this scientific research achievement with independent intellectual property rights, Shanghai Tongji Kelan Environmental Protection Equipment Engineering Co., Ltd. has scientifically produced the high-temperature denitrification catalyst and applied it to the pilot-scale test of the waste heat of coal-bed methane power generation in Shanxi Coal Group and achieved excellent denitrification effect . The results have broad market prospects in the field of denitrification of coalbed methane, natural gas flue gas and kiln flue gas. The team researched and developed low temperature (200 ° C) denitrification catalyst and serialized de-nitrification equipment won awards such as Golden Bridge Award of China Market Association, Third Prize of Shanghai Science and Technology Progress Award, etc. They are widely used in stainless steel pickling, wet smelting and catalyst preparation , Chemical manufacturing industries such as flue gas denitrification.
