Abstract (en)
[origin: WO0244114A1] The production of alkyl aryl compounds can be achieved by the following steps: 1) production of an olefin mixture, comprising, as a statistical mean, predominantly single-branched C>10-14< olefins, by means of a) reaction of a C>4< olefin mixture on a metathesis catalyst to give an olefin mixture containing 2-pentene and/or 3-hexene and optional separation of 2-pentene and/or 3-hexene, followed by dimerisation of the obtained 2-pentene and/or 3-hexene on a dimerisation catalyst to give a mixture containing C>10-12< olefins and optional separation of the C>10-12< olefins, or b) extraction of predominantly single-branched paraffins from kerosene fractions and subsequent dehydrogenation, or c) Fischer-Tropsch synthesis of olefins or paraffins, whereby the paraffins are dehydrogenated, or d) dimerisation of short-chain internal olefins, or e) isomerisation of linear olefins or paraffins, whereby the isomerised paraffins are dehydrogenated, 2) reaction of the olefin mixture obtained in step 1) with an aromatic hydrocarbon in the presence of an alkylation catalyst containing zeolites of the faujasite type.
