Abstract: Described is a device and a method for separation of fluid mixtures, the device comprising a porous and sorptively-acting body being at least at one of its external surfaces in direct contact with a separating layer, provisions for asymmetrical heating for targeted introduction of thermal desorption energy into the porous body, as well as provisions for removing substances permeating through the separating layer, the separating layer consisting of polymers, carbon fibers, and carbon-like and/or metallic materials and/or oxidic and non-oxidic ceramic materials and/or glasses.

Abstract: The invention relates to a method for reducing the carbon dioxide concentration in air of a closed or partially closed unit of space. The inventive method may comprise the steps of removing an air flow from the unit of space, guiding the air flow in a membrane system that may contain at least one membrane module having a CO2/O2 selectivity of greater than 2, removing the carbon dioxide permeated through the membrane, and returning the air flow that has been depleted of carbon dioxide in the membrane system to the unit of space. The inventive method may be optionally combined with an oxygen enrichment method. The invention also relates to corresponding devices for carrying out the inventive method.

Abstract: The invention relates to a method for separating a fluid mixture consisting of at least two components. The inventive method comprises the following steps: contacting the fluid mixture at a first, lower temperature in a first operating zone with a carbon membrane which is arranged adjacent to a surface of a porous transport matrix or which is applied on a surface of the matrix, whereby at least one fluid component is adsorbed and at least one component of the fluid mixture preferably permeates the membrane; heating a surface spatially distant from the membrane and/or a part of the porous transport matrix to a second, higher temperature which facilitates the thermal desorption of adsorbed components in a second operating zone; separately removing the fluid mixture depleted by the at least one permeated component from the first operating zone and the fluid mixture enriched with the at least one permeated component from the second operating zone.
