摘要
根据我国镍系顺丁橡胶的生产数据和工艺方案,对釜式丁二烯聚合工艺进行了动力学分析和工程分析。由分析结果推断,镍系催化剂的催化活性具有依温性和依时性两大特性,而釜式反应器的热不穗态操作特性则是过程偏离优化操作的主要根源。
Based on the practical data and operation program , both kinetic and engineering analyses of nickel catalyzed butadiene rubber production by tank reactor in China were reviewed .The analytical results showed that there are two characteristics for the nickel catalyst system ,temperature dependence and time dependence to activity of catalyst ; In chemical reaction engineering sector ,the heat - unstable characteristic for tank reactor is the main source which causes the departure from the optimum operation state.
