From four parts , the paper expounds upon the feature of the new process and the plant arrangement , and discussed emphatically the procedure of manufacturing 1 - hexene from 2 - butene isomerazation reaction & 1 - butene automethathesis and hexene isomerazation reaction 摘要论述了天津石化乙烯回收新技术扩大中试装置的工艺特点、新工艺的主要流程和设备布置的设计方法。
2.
In part 3 , the in - situ copolymerization of ethylene was investigated by the combinations of the cobalt - based catalyst and the metallocene to prepare short - branched polyethylene . the major oligomers catalyzed by the cobalt - based catalyst 5 , 6 and 7 werel - butene , and the minor were 1 - hexene . the comonomer effects were also observed 在双亚胺基吡啶钴配合物与茂金属复配催化乙烯原位共聚制备短支链支化聚乙烯中，合成了3种双亚胺基吡啶钴配合物，研究了反应条件对其催化乙烯齐聚活性和所得产物碳数分布的影响。
