应用75 kg/h聚丙烯中试装置评价了A、B、C、D 4种聚丙烯催化剂的性能,考察了催化剂的活性、氢调敏感性、等规度、聚合物细粉等性能。结果表明,B、C、D 3种国产催化剂活性高于进口催化剂A,且3种国产催化剂的氢调敏感性好、等规指数可调,能够适应聚丙烯中试装置生产的需要,但D催化剂聚合物细粉较多。B、C、D国产催化剂生产的T30S产品,其质量能够达到标准要求。
The performances of four kinds of polypropylene catalysts A, B, C and D were evaluated using a 75 kg / h polypropylene pilot plant. The properties of catalysts such as catalyst activity, hydrogen sensitivity, isotacticity and polymer fines were investigated. The results showed that the activity of three domestic catalysts B, C and D was higher than that of imported catalyst A, and the three domestic catalysts showed good hydrogen sensitivity and adjustable isotactic index, which could meet the needs of polypropylene pilot plant. However, D Catalyst polymer powder more. B, C, D domestic catalyst production of T30S products, the quality can meet the standard requirements.
