Industrial application of catalyst BCE-H 200 in high density polyethylene unit
Injection resin and film resin was pro-duced by domestic catalyst BCE-H 200,which su-perseded 2 imported catalysts(Z 501 and Z 509),in the high density polyethylene unit of SINOPEC-SK(Wuhan)Petrochemical Co Ltd,which applies Hostalen ACP technology.Comparing three catalysts'activity,and particle size distributions,bulk density of the resin powders,and the properties of resins produced by three catalysts was analyzed.The results showed that the activity of BCE-H 200 was 49.2％higher than that of Z 509 and was 13.8％lower than that of Z 501,while the sensitivity of hydrogen re-sponse of BCE-H 200 was lower than both the Z 501's and Z 509's.The particle sizes of resin powders of BCE-H 200 were more concentrated and larger,while the bulk density of resin powders of BCE-H 200 was less than Z 501's and Z 509's.Comparing with Z 501,the injection resin produced by BCE-H 200 had higher rigidity and lower impact property,while its molecular weight distribution was wider.The film resin produced by BCE-H 200 was similar to the resin produced by Z 509 in the aspects of physical and mechanical properties,while its relative molecular weight distribution was wider.
