基于专利分析的合成氨催化剂发展态势研究
Research on development trends of synthetic ammonia catalysts based on patent analysis
通过分析1900年以来全球合成氨催化剂专利现状,从专利申请趋势、专利申请人及专利地域布局、技术构成等维度,探究了该领域技术发展趋势。合成氨催化剂技术的发展历程中有两次较为显著的专利申请高峰期:第1次出现在20世纪20年代前后,其研究重点是适用于哈伯法的催化剂;第2次则始于2015年,这一阶段的研究重点转向了温和条件下的新型合成氨催化剂。现阶段围绕合成氨催化剂专利申请,国外以热催化技术为主,国内则以电催化技术为核心。
Through analyzing the global patents situation of catalysts for synthetic ammonia since 1900,this study examines the technological development trends in this field from various dimensions,including patent application trends,geographical layout of patent applicants and patents,and technological composition.The technology development of synthetic ammonia catalysts has experienced two peaks of patent applications.The first peak arose around 1920,which focusing on the catalysts for Haber-Bosch process,and the second peak started 2015,which focused on novel catalysts for ammonia synthesis under mild conditions.Currently,global patent applications about synthetic ammonia catalysts are dominated by thermal catalysis technologies,whereas electrocatalysis technology has emerged as the predominant research focus and core technology in China.
