    摘要： The present invention relates to a method for cleaning a reactor having a tendency of fouling by deposition of solids, wherein a hot solvent, in which the solids are soluble and which has a temperature of at least about 75° C., is applied to the reactor, the solids being substantially dissolved and the dissolved solids being discharged from the reactor, wherein the method is carried out without opening the reactor to atmosphere.

    摘要： A process for the preparation of linear α-olefin oligomers comprising: providing a cascade of at least 3 reaction vessels connected in series, and adding at least one solvent, at least one homogeneous oligomerization catalyst and ethylene the first reaction vessel, then conducting an oligomerization reaction in the first reaction vessel for a period of time sufficient to start α-olefin formation, thereafter transferring at least a part of the content of the first reaction vessel to a second reaction vessel with or without additional ethylene, then conducting the oligomerization reaction in the reaction vessel for a second period of time sufficient to continue α-olefin formation, then transferring at least a part of the content of the second reaction vessel to the next reaction vessel in the cascade with or without additional ethylene and then conducting the oligomerization reaction in that reaction vessel for a period of time sufficient to continue α-olefin formation, and isolating linear α-olefin oligomers from the last reaction vessel.
