| 摘 要： | 目的/意义]温室气体排放导致的气候和环境变化已经给人类带来恶劣影响,碳捕捉、碳利用和碳封存是控制大气中温室气体含量的重要手段,有助于实现我国“碳达峰”和“碳中和”目标。方法/过程]从德温特世界专利索引数据库(DII)检索有关“碳捕捉”“碳利用”和“碳封存”的专利,开展专利分析:(1)对专利数量、专利申请时间等指标进行统计分析;(2)对专利公开国家/地区、专利权人以及研发团队合作关系等进行关联关系分析;(3)使用CiteSpace工具进行文本主题聚类分析和热点分析,基于专利被引频次分析“碳捕捉”“碳利用”和“碳封存”领域的关键技术主题,以掌握该领域的技术研发态势。结果/结论]全球“碳捕捉”“碳利用”和“碳封存”技术的研发于20世纪90年代中期开始进入发展期;中国和美国的专利量领先全球,是全球最重要的技术布局市场;较多日本企业在该领域申请了专利,且全球企业间技术研发的合作较少;“碳捕捉”的材料、设备、系统以及“碳封存”的储存罐是研发热点,但“碳捕捉”技术较多关注能源开采、发电、采矿冶炼等工业生产过程,对大气中二氧化碳捕捉技术研发较少。从高被引专利来看,中国是该技术领域最重要的技术布局市场,在传统能源开采、工业生产、煤火发电等行业的碳捕捉方法、设备和系统技术研发较多;二氧化碳的再利用如防爆防雷、农业生产等技术研发较少;相对于“碳捕捉”和“碳利用”技术来说,“碳封存”技术则较为空白,这与“碳封存”技术的实现条件较为复杂以及成本较高有关。

| Abstract: | Purpose/significance]Climate and environmental changes caused by greenhouse gas emissions have already brought severe effects on humans.Carbon capture,carbon utilization,and carbon storage are important means to control the content of greenhouse gases in the atmosphere,and help to achieve"carbon peak"and"carbon neutralization"goal in China.Method/process]Search patents related to"carbon capture","carbon utilization"and"carbon storage"from the Derwent World Patent Index Database(DII),and conduct patent analysis:(1)statistical analysis of indicators such as the number of patents and patent application time;(2)analyze the relationship between patent disclosure countries/regions,patentees,and R&D team cooperation;(3)use CiteSpace tools to perform text topic clustering analysis and hot spot analysis,and analyze key technical topics in the fields of"carbon capture","carbon utilization"and"carbon storage"based on the frequency of patent citations to grasp the technology research and development trend in this field.Result/conclusion]The research and development of global"carbon capture","carbon utilization"and"carbon storage"technologies began to enter the development phase in the mid-1990s;China and the United States lead the world in patent volume and are the most important technology deployment market in the world;more Japanese companies have applied for patents in this field,and there is less cooperation in technology research and development among global companies;"Carbon capture"materials,equipment,systems,and"carbon storage"storage tanks are research and development hotspots,but"carbon capture"technology focuses more on industrial production processes such as energy extraction,power generation,mining and smelting,and research and development of atmospheric carbon dioxide capture technology less.From the perspective of highly cited patents,China is the most important technology deployment market in this technology field.There are more research and development of carbon capture methods,equipment and system technologies in industries such as traditional energy mining,industrial production,and coal-fired power generation;reuse of carbon dioxide,such as explosion-proof and lightning protection,agricultural production,and other technologies are less developed;compared with"carbon capture"and"carbon utilization"technologies,"carbon storage"technology is relatively blank,which is in line with the realization of"carbon storage"technology the conditions are more complicated and the cost is higher. |
