Low Carbon Institute's denitration catalyst regeneration won the China Patent Silver Award

　　On July 14, the State Intellectual Property Office announced the winners of the 21st China Patent Awards. The invention patent of the National Energy Group Low Carbon Institute "a method for regenerating a denitrification catalyst and a regenerated denitrification catalyst and its application" won a Chinese patent Silver award. "

　　"A method for regenerating a denitrification catalyst and a regenerated denitrification catalyst and its application" is that the Low Carbon Institute aims at the deactivation of denitration catalysts in coal-fired power plants and provides a catalyst regeneration method that uses valuable elements in spent catalysts as active supplementary liquid The method, through a series of core technologies such as big data rapid diagnosis technology, targeted cleaning and active component gradient distribution, solves the problem of synergistic improvement of the activity and mechanical strength of the regenerated catalyst. The waste catalyst is 100% recycled and the performance of the regenerated catalyst can be restored. To 95%-105% of new catalyst, reduce catalyst cost by more than 40%. All indicators are better than similar foreign products, reaching the international advanced level.

　　Low Carbon Institute has established a comprehensive intellectual property protection strategy around the core technology of denitration catalyst regeneration. Through analysis, analysis, construction, and optimization of technical solutions, the core patents, proprietary technologies, and defensive patent layouts have been constructed, and their content comprehensively covers new denitrification catalyst preparation technology, denitrification catalyst recovery and regeneration technology, and catalyst evaluation and detection technology. A total of 59 patents have been applied for, including 52 invention patents, 4 foreign patents, and 15 patents have been authorized. At the same time, the Low Carbon Institute has built a multi-dimensional, multi-level protection network around this core technology through patents, technical standards, trademarks, and software copyrights, laying a solid foundation for the commercialization of denitrification catalyst technology. Since 2016, this technology has been applied in nearly 100 units, providing strong support for the clean utilization of coal and environmental protection in my country, and has important economic, environmental and social benefits.

　　The China Patent Award was jointly established by the State Intellectual Property Office and the World Intellectual Property Organization to encourage and commend patentees and inventors (designers) who have made outstanding contributions to technological (design) innovation and economic and social development. It is a field of Chinese patents. The highest honor, the award emphasizes the technical level and innovation height of the patent itself, also pays attention to its application in the market transformation process, and also puts forward requirements for its protection status and management status.
