Abstract:
     A process for preparing alpha-olefin by ethylene oligomerization uses jet circulating reactor as chain growing one for full utilization of high-pressure ethylene and reduction of cost. Two-stage polymerization is used to obviously increase selectivity of hexene-1 and octylene-1 as target products up to 90% or more. Spray reactor is used as displacement one for lowering the gas/liquid ratio of displacing agent and alkyl aluminium, so treating displacing agent easily.
