煤炭直接液化技术研发进入第二次成长期——煤炭直接液化相关技术全球专利布局分析

Patent-based Technology Analysis of Global Direct Coal Liquefaction Technology: Direct Coal Liquefaction Technology R&D Entered into the Second Growth Stage

随着能源安全形势的日益严峻,全球煤炭直接液化相关技术的研发已进入第二次成长期。通过专利信息分析的方法,研究全球煤炭直接液化相关技术专利活动与世界原油价格变化的关系,以及该领域技术研发趋势和专利布局的情况,并在此基础上对国外在华专利进行了分析,最后从专利的角度对中国煤炭直接液化产业的发展提出了建议。

With the Energy Security＇ s increasing seriousness, the R＆D of global direct coal liquefaction technology has entered into the second growth stage. By patent information analysis, the paper studied the relationship between global direct coal liquefaction technology research and development and world crude oil price changes, as well as the development status and patents in this field, and further analyzed related patents in China. Some suggestions are also provided for China＇s direct coal liquefaction industry from the perspective of patent at the final part of the paper.
