单乙醇胺（MEA）吸收法被认为是较具可行性的 CO2捕集技术之一。从技术竞争与市场应用的角度，本文基于全球专利数据，从专利申请数量、专利覆盖地区、专利引用频次、专利权人合作关系、核心专利等方面分析全球MEA技术研发机构的竞争实力。研究结果发现，美、日、欧的研发机构实力较强；美国、欧洲和中国是MEA专利保护的重点国家和地区；从专利数量来看，法国石油研究院申请的专利最多，日本三菱重工和关西电力、荷兰壳牌公司紧追其后；总体上，美国申请MEA专利的公司与专利数量最多；从MEA专利关注的技术方向看，依次为吸收能力、能耗、水消耗、腐蚀和降解；从专利战略来看，国外机构更为注重专利在多国的申请保护和核心专利的引用保护。%s:The mono-ethanolamine (MEA) absorption method is considered to be one of the more viable CO2 capture technologies. In view of technological competition and market application,based on patent analysis the competitiveness of the global MEA technology research and development institutions are compared through patent application quantity,defend regions,citations frequency, collaborating relations among patent holders,core patents and so on. The USA,China and Europe are important areas of patent protection,while the institutions from the USA,Japan and Europe have stronger competitiveness. French Petroleum Institute (IFP) has the most MEA patents,followed by Japan’s Mitsubishi Heavy Industries and Kansai Electric Power Co. and Dutch Shell,while the USA has the most institutions for MEA patents. The technologies of MEA patents include MEA absorptive capacity,energy consumption,water consumption,corrosion and degradation. Compared with domestic institutions,foreign institutions pay more emphasis on patent applying protection over many countries and the cited protection of core patents.
