摘要
在30万t/a环管聚丙烯(PP)装置上,进行了国产CMAX120型催化剂的应用试验,并与该装置原用进口催化剂作了对比。结果表明,与进口催化剂相比,CMAX120型催化剂的平均活性略低、氢调性略差、等规度调节性略优;2种催化剂所得产品PP粉料的粒径分布相差较大,其中CMAX120型催化剂所产PP中细粉含量明显增加,平均粒径较小;CMAX120型催化剂所产PP除清洁度略差于进口催化剂生产的PP产品外,其他质量指标均相当,产品质量合格。
The application of home-made catalyst CMAX 120 in a loop reactor with yield of 300 kt/a polypropylene (PP) was carried out.A comparison was made between the catalyst CMAX 120 and the import one.The results showed that the CMAX 120 catalyst, compared with import one,was possessed of slightly lower average catalytic activity,lower susceptibility of hydrogen adjustment and a little higher adjusting ability of isotacticity.The particle size distributions of PP produced by the two catalysts respectively were dif...
