The catalytic activities and selectivities of Ind 2Zr(OC 6H 4 p Me) 2 and Et n AlCl 3- n ( n =2, A; n =1.5, B; n =1, C) as co catalyst three binary catalyst systems on ethylene oligomerization have been studied at different reaction temperatures, aging temperatures and various reaction time. Under the same reaction condition the catalytic activities of three systems are in the following order: A>B>C. Under optimal reaction conditions, the activity of Ind 2Zr(OC 6H 4 p Me) 2/A is 1 666 g/(g Zr· h) , the selectivity of C 4-10 olefins is 92.7% and the selectivity of α C 4-10 linear olefins is 86.0 %.
