| abstract |
The present invention relates to a process for preparing polyolefins, wherein the feedstock comprising n-olefins or n-olefin mixtures comprises: a) a combination of a reactor and a distillation column comprising at least one catalyst bed, Or b) a distillation tower connected to at least one side reactor comprising at least one catalyst bed or a side stream to be combined with the feedstock to recover unreacted n-olefins from the distillation column. Passed through a catalytic distillation apparatus comprising any of the combinations of dimers, dimerizes in the presence of a solid acidic catalyst, and the reaction product due to dimerization is hydrogenated. |
