| 摘要 |
The present invention relates to a method for preparing olefin comonomers from ethylene. The comonomer generated can be used in a subsequent process, such as a polyethylene polymerization reactor. The comonomer generated can be transported, optionally without isolation or storage, to a polyethylene polymerization reactor. One method includes the steps of: feeding ethylene and a catalyst in a solvent/diluent to one or more comonomer synthesis reactors; reacting the ethylene and the catalyst under reaction conditions sufficient to produce an effluent comprising a desired comonomer; forming a gas stream comprising unreacted ethylene, and a liquid/bottoms stream comprising the comonomer, optionally by passing the effluent to one or more downstream gas/liquid phase separators; and purifying at least a portion of said liquid/bottoms stream by removing at least one of solid polymer, catalyst, and undesirable olefins therefrom.
