Patent ID: 7858833

Claim:
A method for preparing linear alpha olefin comonomers from ethylene monomer comprising the following steps: providing one or more comonomer synthesis reactors configured in series, and one or more downstream gas/liquid phase separators configured in series; feeding an ethylene monomer, and a catalyst in a solvent to said one or more comonomer synthesis reactors; reacting in said one or more comonomer synthesis reactors said ethylene monomer and said catalyst in solvent under reaction conditions to produce an effluent stream comprising unreacted ethylene monomer, said catalyst in a solvent, and comonomer; passing said effluent stream to said one or more downstream gas/liquid phase separators to form a gas stream of said unreacted ethylene monomer, and a liquid stream of said comonomer and said catalyst in a solvent; recycling to said one or more comonomer synthesis reactors said unreacted ethylene monomer and a portion of said liquid stream; and storing a remaining portion of said liquid stream for subsequent processing of said comonomer; wherein said comonomer is selected from the group consisting of 1-butene, 1-octene, 1-decene and mixtures thereof, and said comonomer is said solvent.
