    Abstract: A process is proposed for obtaining a stream of aliphatic hydrocarbons comprising from 4 to 12 carbon atoms per molecule, with an increased proportion of linear alpha-olefins compared to a feed stream of aliphatic hydrocarbons comprising from 4 to 12 carbon atoms per molecule, with a content of linear alpha-olefins, linear internal olefins and dienes, wherein the feed stream is fed to a first distillation zone D 1 having at least 5 theoretical plates, in which the linear alpha-olefins are removed partly or fully as a component of a vapor stream which additionally also comprises the dienes, and at whose lower end a liquid stream is obtained which has been depleted partly or fully of linear alpha-olefins, the liquid stream from the lower end of the first distillation zone D 1 is introduced into a isomerization unit which is equipped with an isomerization catalyst over which the linear internal olefins are isomerized partly or fully to linear alpha-olefins, and the linear alpha-olefins formed in this way are removed as a component of a vapor stream ascending into the first distillation zone D 1, the vapor stream ascending out of the first distillation zone D 1 enters a selective hydrogenation unit comprising a second reactive distillation zone RD 2 in which at least a portion of the dienes are hydrogenated selectively to olefins over a low-isomerization selective hydrogenation catalyst to obtain a vapor stream which is drawn off, condensed fully or partly and drawn off as a product stream with an increased proportion of linear alpha-olefins compared to the feed stream, the distillation zone D 1 and the reactive distillation zone RD 2 being integrated in a single reactive distillation column RDK.

    Abstract: Carrying out reactive distillation in the presence of a heterogeneous catalyst suspended as dispersed phase in the liquid comprises continuously removing a part of the suspension containing the catalyst from the column, treating in a preparation stage, and returning the treated catalyst to the column.
