摘要/Abstract

摘要：

采用流化床进行烯烃聚合是聚烯烃制备的核心技术之一，本文以全球聚烯烃流化床技术相关专利为研究对象，从全球专利申请趋势、专利技术来源与布局等角度，研究了全球聚烯烃流化床专利技术的分布情况，并采用文本聚类、技术功效矩阵、合作网络分析等方法，分析领域技术发展趋势、主要技术分布以及全球技术竞争格局，同时针对核心申请人进行重点技术分析，为我国聚烯烃流化床技术的发展提供参考依据。分析表明：聚烯烃流化床领域技术处于技术稳定期，且存在明显的技术垄断现象，美国技术实力最强，中国属于技术输入国，本土技术研发实力与美国存在较大差距；催化剂研究是领域研究的重点方向，围绕聚合反应器方面的研究逐步成为热点；针对冷凝工艺与回收分离工艺的改进探索相对较少，国内企业与研发机构可以作为技术突破的方向。

Abstract:

Using fluidized bed to produce polyolefine is one of the core technologies for polyolefin production. By taking the patents related to global polyolefin fluidized bed technology is the research object, the distribution of global polyolefin fluidized bed patent technology was studied from the perspective of global patent application trend, patent technology source and layout in this review. In the meantime, the development trend, main technology distribution and global technology competition pattern of polyolefin fluidized bed technology are analyzed by adopting the methods of text clustering, technical efficacy matrix and cooperative network analysis. The core applicants' key technology are analyzed, so as to provide reference basis for the development of polyolefin fluidized bed technology in China. The results showed that the technology in the field of polyolefin fluidized bed is in a period of technological stability, and the phenomenon of technological monopoly is prominent. The technical strength of United States is strong, while China is a technology importing country and its local strength was relatively week. There is a big gap in technical strength between China and the United States. Technically, the catalyst research is the key direction in the field, and the research around polymerization reactor had gradually become a hot spot. Meanwhile, the condensation process as well as recovery and separation process are relatively lack of attention, which can be the direction of technological breakthrough for domestic enterprises and R & D institutions.

Key words: polyolefine, polymer, fluidized bed, patent analysis, catalyst, reactors
