Ethylene Oligomerization Catalyzed by Ind2Zr(OC6H4-p-Me)2/EtnAlCl3-n

Abstract

Abstract: The catalytic activities and selectivities of Ind 2Zr(OC₆H₄-p-Me)₂ and Et_nAlCl_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(OC₆H₄ p Me)₂/Ais 1666 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 %.

Key words: Ethylene, Oligomerization, Ziegler-Natta catalyst, α-Olefin
