A process for the production of oligomerized olefins comprising the following steps a) to e): a) purification of an organic composition comprising at least one alkane, at least one olefin and at least one compound containing oxygen and/or sulphur wherein is fed into at least one adsorber in order to obtain an organic composition comprising at least one alkane, at least one olefin and a reduced amount of at least one compound containing oxygen and/or sulphur compared to the respective amount in organic composition, b) oligomerization of organic composition in the presence of a catalyst, wherein at least one of the olefins of is at least partially oligomerized, obtaining an organic composition comprising a reduced amount of at least one olefin and an increased amount of at least one oligomerized olefin, compared to the respective amounts in; c) distillation of organic composition in a distillation column, wherein i) an organic composition is obtained from the upper part of and comprises at least one alkane, at least one olefin and a reduced amount of at least one oligomerized olefin compared to the respective amount in, ii) an organic composition is obtained from the lower part of and comprises at least 80 % by weight, preferably at least 95 % by weight of the at least one oligomerized olefin present in organic composition; d) hydrogenation of organic composition to obtain an organic composition comprising at least one alkane and a further reduced amount of the at least one olefin and/or of the at least one oligomerized olefin compared to organic composition, e) regeneration of at least one of the adsorbers employing organic composition as regeneration media. a) purification of an organic composition comprising at least one alkane, at least one olefin and at least one compound containing oxygen and/or sulphur wherein is fed into at least one adsorber in order to obtain an organic composition comprising at least one alkane, at least one olefin and a reduced amount of at least one compound containing oxygen and/or sulphur compared to the respective amount in organic composition, b) oligomerization of organic composition in the presence of a catalyst, wherein at least one of the olefins of is at least partially oligomerized, obtaining an organic composition comprising a reduced amount of at least one olefin and an increased amount of at least one oligomerized olefin, compared to the respective amounts in; c) distillation of organic composition in a distillation column, wherein i) an organic composition is obtained from the upper part of and comprises at least one alkane, at least one olefin and a reduced amount of at least one oligomerized olefin compared to the respective amount in, ii) an organic composition is obtained from the lower part of and comprises at least 80 % by weight, preferably at least 95 % by weight of the at least one oligomerized olefin present in organic composition; i) an organic composition is obtained from the upper part of and comprises at least one alkane, at least one olefin and a reduced amount of at least one oligomerized olefin compared to the respective amount in, ii) an organic composition is obtained from the lower part of and comprises at least 80 % by weight, preferably at least 95 % by weight of the at least one oligomerized olefin present in organic composition; d) hydrogenation of organic composition to obtain an organic composition comprising at least one alkane and a further reduced amount of the at least one olefin and/or of the at least one oligomerized olefin compared to organic composition, e) regeneration of at least one of the adsorbers employing organic composition as regeneration media.
