WebSpheripol 工艺可生产丙烯均聚物、无规共聚物以及乙丙抗冲共聚物。. 生产均聚和无规共聚产品时采用两个串联的环管反应器。. 其中无规共聚产品的第二、三单体分别为乙烯和丁烯 (乙烯和丁烯均为少量)，有时也只加入第二单体乙烯。. 而抗冲聚丙烯为嵌段聚合 ... WebUntil about 2010, PE/PP plant capacities of 300,000 tpy–400,000 tpy were considered standard for a large plant. However, PE/PP technology licensors have kept up the pace by offering capacities in the range of 450,000 tpy–650,000 tpy, depending on the product mix.

WebSpheripol工艺是运用液相预聚合同液相均聚合和气相共聚相结合的聚合工艺。 该工艺于1983年工业化，丙烯（或丙烯和乙烯）经过精制，加入液相环管反应器，经矿物油稀释的催化剂和少量的丙烯在预聚合反应器中预聚后，加入环管反应器。 WebProcess Economics Program Report 128C. Published November 2002. This report continues our evaluation of polypropylene processes. Isotactic polypropylene produced with metallocene catalyst represents less than 0.5% of the total global polypropylene capacity. The vast majority of polypropylene is produced with Ziegler-Natta catalyst. christoffer jonsson
