中文摘要：

以单乙醇胺（MEA）吸收法为主的脱碳技术被认为是较具可行性的CO2捕集技术。本文主要针对MEA脱碳技术开展专利分析,建立MEA技术专利分析方法,研究认为基于二氧化碳捕集、运输和封存（CCS）应用的MEA脱碳技术在近十年得到大幅增长,其中增长较快的国家有美国、中国、日本、澳大利亚等,中国和韩国在近3年尤其增长较快;各国MEA脱碳技术专利的侧重点和优势各不同,美国、日本、俄罗斯等国专利较为倾向烟气脱碳、装置、材料等实际应用,中国则倾向于MEA基础方法研究,该研究结果有望为我国MEA脱碳技术研发创新、专利申请与保护提供参考借鉴。

英文摘要：

Mono-ethanol amine（MEA） absorption technology for decreasing the emission of carbon dioxide is considered to be one of the most viable carbon dioxide capture,transportation and storage（CCS） capture technologies. Aiming at the patents of MEA technologies and through establishing the patent searching and analysis methods,it is thought that the MEA patents based on CCS have increased quickly in recent ten years. There are many MEA patents in American,China,Japan and Australia. Especially,China and Korea have a lot of MEA patents in recent three years. Different countries have different emphases and superiorities in MEA patents. American,Japan,Russian and other countries may focus on MEA practical application patents including decreasing-carbon from gas,equipment,material and so on,while China is inclined to studies on basic methods of MEA. These results will help to supply the reference for Chinese MEA technology RD and their patent applications and protection.
