摘　　要：为捕捉碳中和技术的发展热点,从Derwent Innovation获取碳中和技术相关专利,借助ITGInsight工具,分析碳中和技术的时间和空间发展特征并追踪热点技术。结果表明:我国碳中和技术专利申请量世界第一,在近两年出现爆发式增长,但尖端技术领域稍有逊色;我国与美国、日本有很强的技术关联;化工技术和多领域交叉技术是碳中和目标的关键发力点和重要实现路径。同时,烟气、一氧化碳、碳酸钙、节能、电能和低成本等成为当前重点研究主题,当前碳中和技术热点更集中于化工和交叉领域,立足我国国情,化工工艺的催化技术、液态阳光技术、碳捕集技术、电力的“源-网-荷-储”协同技术、CCUS与水泥钢铁耦合减排技术、风电光伏的大规模消纳与氢能耦合技术将是未来碳中和技术发展的重中之重。基于以上结论,对未来碳中和技术的发展提出了建议。In order to capture the development hotspots of carbon neutral technology,carbon neutral technology related patents were obtained from Derwent Innovation,the temporal and spatial development characteristics of carbon neutral technology were analyzed,and the hotspot technology was tracked with the help of ITGInsight tool.The results showed that,China ranked first in the world in terms of patent applications for carbon neutral technology,and had seen explosive growth in the past two years,but the cutting-edge technology areas were slightly inferior;China had strong technological connections with the United States and Japan;Chemical technology and multi-domain crossover technology were the key launching points and important realization paths for carbon neutral goals.At the same time,flue gas,carbon monoxide,calcium carbonate,energy saving,electric energy and low cost had become the key research themes,and the current carbon neutral technology hotspots were more concentrated in chemical and crossover fields,CCUS and cement and steel coupling technology,wind power and photovoltaic large-scale consumption and hydrogen coupling technology would be the most important development of carbon neutral technology in the future.Based on the above conclusions,recommendations for the future development of carbon neutral technologies were put forward.
