Application of homemade 5th generation non-PAEs catalyst in Unipol PP process
Application of the domestic 5th generation non-phthalic acid ester(PAEs)catalyst,SUG-H,in a 400 kt/a Unipol polypropylene process was introduced.The adaptability of SUG-H catalyst and product properties it produces were evaluated.The results show that due to the non-PAEs internal donor and special production method,the composition,morphology,particle size and distribution of SUG-H catalyst are quite different from those of the reference catalyst.The unit operates stable when SUG-H catalyst is applied,and the catalyst has good hydrogen response and high activity.The polymer powder has a medium bulk density,narrow particle size distribution,good morphology and very low fines,which is perfect for Unipol PP process.
