| titleOfInvention | Method and apparatus for producing alpha-olefins |
| abstract | Disclosed is a method (100) for the production of linear alpha olefins in which ethylene in a feed mixture is catalytically oligomerized (1) to obtain alpha-olefins having different chain lengths and secondary Product mixture of compounds. In the primary fractionation step (2), at least a portion of the product mixture is used to form the primary fraction, and in the secondary fractionation step (4), at least a portion of the primary fraction is used to form the secondary fraction. The primary fractionation step (2) and the secondary fractionation step (4) are carried out in such a way that the primary fraction and the secondary fraction contain predominantly one alpha-olefin and are depleted or free of other alpha-olefins, and the primary fraction contains an alpha-olefin. one or more secondary compounds, and the secondary fraction has a lower content of the one or more secondary compounds than the primary fraction. In an intermediate step (3) performed on at least a portion of the primary fraction between the primary fractionation step (2) and the secondary fractionation step (4), the one or more secondary compounds are at least partially converted into one or more Successor compounds, and the one or more successor compounds are at least partially eliminated in the secondary fractionation step (4). The intermediate step (3) is carried out in such a way that at most 0.8% of the alpha-olefins mainly contained in the primary fraction or the portion of the primary fraction subjected to the intermediate step are converted. Intermediate steps are carried out using alumina-based catalysts. |
