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

Abstract: A separation process, for hydrocarbon liquids, involves one or more membrane stages, where the pressure of the feed liquid is raised, e.g. to 1.5-200 bar absolute, and then the feed partially or completely vaporized by heating, before supplying it to a membrane module, e.g. at a temperature of -20 to +300 degreesC. Between 90 -99.9% of the energy input is provided as thermal energy.

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 reaction membranes that contain a selective oxidation catalyst disposed on a ceramic membrane that selectively conducts oxide ions and that is composed of (Sr1-xCax)1-yAyMn1-zBzO3- delta , wherein A represents Ba, Pb, Na, K, Y, an element of the lanthanide group or a combination of these elements, B represents Mg, Al, Ga, In, Sn, an element of the 3d or 4d period or a combination of these elements, x is a number of from 0.2 to 0.8, y is a number of from 0 to 0.4, z is a number of from 0 to 0.6 and delta is a number that results from the principle of electroneutrality on the basis of x, y and z. The inventive reaction membranes are suitable for use in oxidative reactions of hydrocarbons in which oxygen is used.

Abstract: The invention relates to a method for trioxan isolation from an aqueous mixture basically consisting of trioxan, water and formaldehyde. The method is characterized in that trioxan is withdrawn from the mixture by pervaporation and in that the trioxan enriched mixture (permeate) is separated by trioxan rectification and an azeotropic mixture of trioxan, water and formaldehyde.
