摘要
变压吸附是高效分离工业气体的有效手段。本文以CNABS数据库和DWPI数据库收录的变压吸附分离工业气体领域的专利申请文献为研究对象,对变压吸附分离工业气体领域的技术发展现状、申请人信息、专利价值等方面进行了分析。研究表明,我国申请人在变压吸附分离工业气体领域已经建立了专利数量上的优势,但是在核心技术、行业集中度仍然存在较大的提升空间。基于研究结果,本文还对我国在变压吸附分离工业气体领域的发展提出了建议。
Pressure swing adsorption is an effective means to separate industrial gases. This article takes the patent application literature of the field of pressure swing adsorption separating industrial gases embodied by CNABS database and DWPI database as the investigated object, and analyzes the development status, patent applicant information, and patent value of the patent application of the field. It is showed that applicants of China have established advantage in quantity of patents in the field, and there is still much room for improvement in the nuclear technology and the market centralization. Based on the investigated results, this article also proposes suggestions for the development of pressure swing adsorption separating industrial gases in China.
