    摘要： The present invention relates to a method for processing high molecular weight oligomer waste products formed during the production of linear alpha-olefins by oligomerization of ethylene in a reactor in the presence of a solvent and a catalyst, characterized in that the high molecular weight oligomers are separated in a separation unit from a product stream of the reactor comprising the solvent, the catalyst, linear alpha-olefins and high molecular weight oligomers having a solidification temperature in the range of about 60-100° C., then diluted with a dilution medium and heated to about 130° C. to about 200° C., the diluted high molecular weight oligomers are then transferred to a disposal device, wherein at least some of the dilution medium may be recovered and recycled for addition to the dilution medium.

    摘要： The present invention relates to a method for preparing linear alpha-olefins by oligomerisation of ethylene, comprising the steps of: (i) oligomerising ethylene in a reactor in the presence of a solvent and a catalyst; (ii) transferring a liquid organic outlet stream of the reactor, containing solvent, catalyst, dissolved ethylene and linear alpha-olefins, to a catalyst deactivation section; (iii) deactivating the catalyst by washing the outlet stream with an aqueous basic phase to obtain a deactivated catalyst containing aqueous phase and a water saturated organic phase; (iv) separating the aqueous phase and the organic phase from step (iii); (v) transferring the water saturated organic phase to a distillation column; (vi) distilling the water saturated organic phase; and (vii) separating the distilled organic and aqueous phases.
