Industrial Application of CS-2-G Catalyst in Spherizone Gas Phase PP Plant

Abstract

LHP456J was produced in 300 kt/a Spherizone gas-phase polypropylene plant using CS-2-G/ ZN1l8 as a substitute catalyst for ZN118. The feasibility of mixing CS-2-G catalyst in the Spheri-zone gas-phase polypropylene plant was investigated. The results show that the mixed catalyst CS-2-G/ZN1l8 has strong adaptability to the Spherizone process in the gaseous polypropylene plant. The whole trial process of the plant runs safely and stably, and the product quality is qualified.
