    摘要： Process for the work-up of naphtha, wherein a) naphtha or a stream produced from naphtha in a pretreatment step is separated in a membrane unit into a stream A which is depleted in aromatics and a stream B which is enriched in aromatics, with the aromatics concentration in stream A being from 2 to 12% by weight (step a), b) at least part of the substream A is fed to a steam cracker (step b), c) at least part of the substream B is fed to a unit in which it is separated by means of a thermal process into a stream C which has a lower aromatics content than stream B or a plurality of streams C′, C″, C′″ . . . which each have lower aromatics contents than stream B and a stream D which has a higher aromatics content than stream B or a plurality of streams D′, D″, D′″ . . . which each have higher aromatics contents than stream B (step c), and d) the stream C or at least one of the streams C′, C″, C′″, in each case in part or in its entirety, is added to the feed to the steam cracker or fed into the steam cracker itself (step d).

    摘要： The present invention relates to a process for preparing oligomers consisting mainly of repeating units derived from 1- or 2-butene from a hydrocarbon stream consisting substantially of branched and linear hydrocarbon compounds having 4 carbon atoms, and comprising olefinic branched and linear hydrocarbon compounds having 4 carbon atoms (C4 starting stream) by a. in step a), separating the C4 starting stream into a fraction consisting mainly of linear hydrocarbon compounds having 4 carbon atoms (l-C4 fraction) and a fraction consisting mainly of branched hydrocarbon compounds having 4 carbon atoms (b-C4 fraction), by contacting the C4 starting stream with a membrane which is easier to pass for linear hydrocarbon compounds having 4 carbon atoms than for branched hydrocarbon compounds having 4 carbon atoms, b. in step b), optionally after removing butanes, oligomerizing the olefinic hydrocarbon compounds having 4 carbon atoms present in the l-C4 fraction, c. in step c), subjecting the olefinic hydrocarbon compounds having 4 carbon atoms present in the b-C4 fraction to one of the following steps: c1. reaction with methanol to give methyl tert-butyl ether (step c1) c2. hydroformylation to give substantially isovaleraldehyde (step c2) c3. polymerization to polyisobutylene (step c3) c4. dimerization to 2,4,4-trimethyl-1-pentene (step c4) c5. alkylation, substantially to form saturated hydrocarbon compounds having 8 or 9 carbon atoms (step c5).
