摘　　要：大庆石化公司采用硅胶作为载体配制了M-1催化剂，并在线型低密度聚乙烯装置上试生产LLDPE树脂。经过聚合标定，催化剂的活性稳定在4000kg/kg左右，聚乙烯产品堆密度达到350-380kg/m^3,LLDPE聚烯吹制的薄膜雾度有较大程度的改善。Daqing Petrochemical Company used silica gel as carrier for preparation of M-1 catalyst,and made pilot production of LLDPE resin in LLDPE Plant. Through polymerization performance test,the catalyst activity has stabilized at about 4 000 kg/kg, the bulk density of the PE product has been 350~380 kg/m3, and the haze of the film blown from LLDPE has improved significantly.
