摘要: Disclosed is a method for producing membranes comprising at least one solid layer on one side of a porous support by treating the side of the support, which is to be coated, with a synthetic solution that forms the solid layer. The inventive method is characterized in that the space located behind the side of the porous support, which is not to be coated, is filled with an inert fluid during the production of the solid layer on the porous support, 'behind' being from the perspective of the support. The pressure and/or the temperature of the fluid is/are selected such that the synthetic solution is essentially prevented from entering in contact with the side of the porous support, which is not to be coated.

摘要: The invention relates to composite membranes comprising at least one porous carrier layer and at least one microporous separating layer, containing at least one MFI-type zeolite. Said separating layer is produced by hydrothermal synthesis. According to the invention, the molar ratio of silicon to aluminium is higher than 120, and the carrier layer contains less than 10 wt. % of aluminium in the elementary or chemically bonded form in a region of at least 100 nm adjacent to the separating layer.

摘要: Disclosed is a method for processing naphtha, according to which a) naphtha or a stream generated from naphtha in a preprocessing step is divided into a stream A that is stripped of aromatics and a stream B which is enriched with aromatics in a membrane unit, the aromatics concentration in stream A ranging from 2 to 12 percent by weight (step a); b) partial stream A is directed at least in part into a steam cracker (step b); c) partial stream B is directed at least in part into a unit in which said stream B is divided into a stream C or several streams C' C'', C''',..., which has/have a lower aromatics content than stream B, and a stream D or several streams D', D'', D''',..., which has/have a higher aromatics content than stream B, by means of a thermal process (step c); d) stream C or at least one of the streams C', C'', C''' is delivered as a whole or in part to the feed for the steam cracker or directly to the steam cracker (step d).

摘要: The invention relates to a method for producing oligomers, primarily consisting of repeating units, derived from 1 or 2-butene, from a hydrocarbon stream that essentially consists of branched and linear hydrocarbon compounds with 4 carbon atoms and contains olefinically branched and linear hydrocarbon compounds with 4 carbon atoms (parent stream C4). According to said method, the parent stream C4 is brought into contact with a membrane.
