Title of Invention	PROCESS OF PRODUCING LINEAR & OLEFINS
Abstract	Disclosed is a process of producing linear &-olefins which comprises the steps of: oligomerizing a lower olefin in the presence of a Ziegler-type catalyst; deactivating the catalyst after oligomerization; adding water to a linear &-olefins-containing reaction mixture, in a weight ratio of water to the organic phase in the reaction mixture of 0.2 or above; and stirring the resulting mixture at a temperature of 90degereecelsiyas or above and under a power of 3KW/m3 or above per liquid unit volume to thereby remove an ash content. The disclosed process has a remarkable advantage in that the catalyst and its metal components can be removed to a very low concentration even in the presence of a by-produced polymer.
