中国科学院长春应用化学研究所开发的“3万吨/年稀土异戊橡胶成套工业化技术”成果,在北京通过由中国科学院组织的成果鉴定。专家组认为,该项目整体达到了国际领先水平,标志着我国稀土异戊橡胶生产技术已经走在了世界前列。整套技术主要特点是:以自主开发的催化剂、聚合、凝聚和后处理技术为核心,集成先进的反应器技术、自动控制技术和节能环保技术开发出国内首套3万吨/年稀土异戊橡胶工艺包,并建成国内外单线产能最大的工业生产装置。工艺包设计合理,装置运转平稳,能耗、物耗低,三废排放量少。在提出的稀土催化双烯烃聚合新机理基础上,开发的催化剂具有高活性、高顺式定向性、低成本和产品分 Chinese Academy of Sciences Changchun Institute of Applied Chemistry developed “30,000 tons / year Rare Earth Isoprene rubber industrialization technology” results, passed in Beijing by the Chinese Academy of Sciences, the identification of the results. The expert group believes that the project as a whole reached the international advanced level, marking China’s rare earth isoprene rubber production technology has come in the forefront of the world. The main features of the complete set of technologies are: Developed the first set of 30,000 tons / year rare earth isoprene rubber by integrating advanced reactor technology, automatic control technology and energy saving and environmental protection technology with the core technologies of self-developed catalyst, polymerization, agglomeration and post-treatment Technology package, and built at home and abroad single-line production capacity of the largest industrial production plant. Process package design is reasonable, the device operates smoothly, energy consumption, material consumption is low, less waste emissions. On the basis of the proposed new mechanism of rare earth-catalyzed diolefin polymerization, the catalyst developed has high activity, high cis-orientation, low cost and product
