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: Reactor membranes advantageously useful in oxidation reactions of hydrocarbons involving oxygen comprise a selective oxidation catalyst on a mixed conducting, oxide ion selective ceramic membrane of the composition (Sr1-xCax)1-yAyMn1-zBzO3-delta, where A is Ba, Pb, Na, K, Y, an element of the lanthanide group or a combination thereof, B is Mg, Al, Ga, In, Sn, an element of the 3d or 4d period or a combination thereof, x is from 0.2 to 0.8, y is from 0 to 0.4, z is from 0 to 0.6, and delta is a number, dependent on x, y and z, that renders the composition charge neutral.

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.
