ABSTRACT:
Alpha-olfins containing about 6-14 carbon atoms are made in a dual displacement loop ethylene/tri-lower alkyl chain growth process which includes, in one closed loop, an initial ethylene/triethyl aluminum (TEA) chain growth, C.sub.2-14 olefin separation, 2-stage ethylene displacment, C.sub.2-12 olefin separation and recycle of residual TEA and higher olefins back to the initial ethylene/TEA chain growth. A second closed loop starts with the same ethylene/TEA chain growth product followed by C.sub.4-14 olefin separation, C.sub.4-8 olefin displacement on the bottoms from C.sub.4-14 olefin separation, ethylene chain growth on the C.sub.4-8 olefin displacement product and recycle of this ethylene displacement product back to the olefin separation stage following the initial ethylene/TEA chain growth reaction.
