    摘要： The present invention relates to an in-line method for generating comonomer from monomer, such as ethylene. The comonomer generated is directly transported, without isolation or storage, to a polyethylene polymerization reactor. The in-line method includes the steps of providing an in-line comonomer synthesis reactor and a downstream gas/liquid phase separator prior to the polymerization reactor; feeding ethylene monomer and a catalyst in a solvent and/or diluent to the comonomer synthesis reactor; reacting the ethylene monomer and the catalyst in solvent and/or diluent under reaction conditions to produce an effluent stream including ethylene monomer and comonomer; passing the effluent stream from the comonomer synthesis reactor to the downstream gas/liquid phase separator to separate a gas stream from a bottom stream, wherein the gas stream is a mixture of ethylene monomer and comonomer; and passing the gas stream to the polymerization reactor to provide the necessary comonomer input.

    摘要： The present invention relates to an in-line method for generating comonomer, from monomer, such as ethylene. The comonomer generated is stored prior to transporting to a polyethylene polymerization reactor. The in-line method includes the steps of providing an in-line comonomer synthesis reactor and a downstream gas/liquid phase separator prior to the polymerization reactor; feeding ethylene monomer and a catalyst in a solvent and/or diluent to the comonomer synthesis reactor; reacting the ethylene monomer and the catalyst in solvent and/or diluent under reaction conditions to produce an effluent stream including ethylene monomer and comonomer; passing the effluent stream from the comonomer synthesis reactor to the downstream gas/liquid phase separator to separate a gas stream from a bottom stream, wherein the gas stream is a mixture of ethylene monomer and comonomer; and passing the gas stream to the polymerization reactor to provide the necessary comonomer input.
