Abstract: The invention relates to a method for obtaining aromatics.

Abstract: Process for concentrating at least one chemical from a liquid or gaseous feed mixture comprising the steps (a) contacting a liquid or gaseous feed mixture with a first surface of a composite membrane having two surfaces, wherein said feed mixture comprises—at least one gaseous or liquid diluent and at least one chemical having a vapour pressure in pure form of 0.8 mbar or more at 20° C.

Abstract: The invention relates to a composite material comprising a) a porous matrix of a polymer containing fluorine and having a percentage of tetrafluoroethylene monomer units of at least 95 mol % based on the total of monomer units, b) hydrophobic zeolite particles which are embedded in the matrix and around which matrix filaments extend, and c) at least one metal material. The invention further relates to the use of the composite material for adsorbing organic molecules from a gaseous or liquid mixture of substances that contains at least one organic component, and to a method for removing organic molecules from a gaseous or liquid mixture of substances.

Abstract: The invention relates to granulated zeolites with high adsorption capacity for organic molecules and the use of the zeolites for adsorbing organic molecules from liquids or gas streams.

Abstract: The invention describes a method for enriching at least one component from a gaseous mixture of substances, comprising the steps of (i) contacting a flow of a first gaseous mixture of substances which contains at least one component to be enriched, with a composite material at a first pressure p1 such that the at least one component to be enriched is adsorbed to the composite material and a charged composite material is obtained, said composite material comprising (a) a porous matrix of a fluorine-containing polymer having a percentage of tetrafluoroethylene monomer units of at least 95 mol % based on the total number of monomer units and (b) zeolite particles which are embedded in the matrix and around which matrix filaments extend; (ii) disrupting the flow of the gaseous mixture of substances and (iii) desorbing the at least one component to be enriched from the charged composite material by reducing the pressure to a pressure p2, with p1?p2?200 mbar, such that a second gaseous mixture of substances is prod

Abstract: The invention relates to a method for obtaining organic compounds from biomass, wherein the steps of gas stripping, adsorption from the gas phase, and catalytic reaction are coordinated with each other. The method according to the invention preferably comprises the steps of fermentation, gas stripping, adsorption, desorption, catalytic reaction, condensation, and decantation, which can proceed in parallel. The invention further relates to the coupling of adsorption, desorption, and catalytic reaction by using the same zeolite material for adsorption and catalytic reaction.

Abstract: The invention relates to a method for obtaining ethanol from a carbohydrate-containing raw substrate wherein the ethanol that is produced is separated during fermentation using a carrier gas. The invention further relates to the adsorption of the ethanol from the gas phase to an adsorber, the desorption of the ethanol during a subsequent process step, and to the further concentration of the ethanol.
