摘要： This disclosure relates generally to low temperature steam stripping methods for byproduct polymer and solvent separation from an ethylene oligomerization process. The methods disclosed have been found to separate byproduct polymer from solvent without fouling process equipment or causing other process problems. The byproduct polymer ends up as flowable solid particles in a water stream that may be easily discharged from the process, while solvent is recovered for recycle to the process. In embodiments of the invention, over 90 wt % of the solvent used is recovered and the discharged byproduct polymer is less than 20 wt % solvent.

摘要： The invention relates to olefin oligomerization methods and methods for reducing/inhibiting fouling in olefin oligomerization reactions comprising: contacting, in an oligomerization reactor (e.g., under oligomerization conditions), an alpha-olefin feed, a catalyst having an olefin selectivity of at least 90 mol % to a desired oligomerization product, a polymer anti-foulant, and optionally a diluent; selectively producing an effluent comprising the desired oligomerization product, unreacted olefin, and alpha-olefin-based polymer byproduct that causes fouling. The amount of polymer anti-foulant can be chosen to limit fouling to ≦20 g/kg desired oligomerization product, to remediate ≧3 grams fouled polymer/kg desired oligomerization product, and/or to reduce/inhibit polymer fouling by ≧10% over a selective oligomerization with substantially no added polymer anti-foulant. Advantageously, desired oligomerization product so obtained can also be polymerized/copolymerized with an alpha-olefin such as ethylene.

摘要： Disclosed herein is a method for separating from the reactor effluent of an olefin oligomerization procedure those catalyst materials and polymeric by-products which can cause difficulties in the downstream processing of such effluent. Polymer by-products and catalyst in the effluent are separated from reaction products by flash vaporization utilizing an in-situ hot solvent which is contacted with the effluent and serves as the heating medium to promote this flash vaporization step. Subsequent processing of a liquid portion of the effluent which is left after flash vaporization involves recovery of catalyst and polymeric by-products therefrom in a steam stripping vessel. Also disclosed is a multiple reactor system which can be used for continuous trimerization of ethylene to 1-hexene while at the same time washing polymeric by-products from one of the reactors in the series using a wash oil solvent.
