摘要
采用自主研发的THG催化剂进行工业应用,考察了该催化剂的各项性能及装置运行的平稳性。结果表明,THG催化剂的活性为62.75×104g/g,为进口THB催化剂的11倍;聚合产品堆密度达到0.42 g/cm3,产品的熔融指数调整容易;催化活性释放平稳;用THG催化剂生产的粉状HDPE的各项性能均能满足制品的要求。
Using the self-developed THG catalyst in industrial applications,the performance of the catalyst and the stability of the plant operation was studied.The results showed that,the activity of the catalyst(based on the yield of HDPE pergram of Ti)is 62.75×104g/g,and that is 11 times of the imported THB catalyst;the bulk density of the polymerization products reaches to 0.42 g/cm3,which makes the melt index easy to be adjusted;the activity of the catalyst is released steadily;the process parameters are steady;the polymerization and liquor recovery system has no abnormal changes;all the properties of the granular HDPE products produced using the THG catalyst can meet the requirements of users.
