    Abstract: 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).

    Abstract: The fluid de-ionizing medium is used for intermittent or continuous removal or ions from a cooling medium for a fuel cell using a de-ionizing device (23), inserted in the cooling medium circuit (20) for a fuel cell device (10) having at least one fuel cell (11), with mixing of the fluid-de-ionizing medium and the cooling medium directly or via a membrane. Also included are Independent claims for the following: (a) a method for de-ionizing a cooling medium for a fuel cell; (b) a fuel cell device with at least one fuel cell and at least one fuel cell cooling circuit

    Abstract: The invention relates to a method and device for deionizing a cooling medium of a fuel cell that circulates inside a cooling circuit. The invention is characterized in that a liquid deionizing agent is permitted to act, at least intermittently, upon the cooling medium whereby enabling the deionizing agent to absorb ions from the cooling medium. To this end, the inventive fuel cell aggregate (10), which comprises at least one fuel cell (11) and at least one cooling circuit (20) for the fuel cell, has, inside the cooling circuit (20), at least one deionization device (23), inside of which a liquid deionizing agent can act upon the cooling medium. The deionization device can comprise static mixers (28, 34) downstream from which membrane separators (29, 35) are connected.
