Abstract: The invention relates to a method for producing flexible and porous adsorbents based on oxidic and/or non-oxidic ceramic material containing carbon. The inventive method is characterized by the following steps: (a) producing a flat base matrix whose constituents are held together essentially by hydrogen bridge bonds, on a machine suited for producing paper; (b) applying and/or impregnating the surface of the base matrix, on one or both sides, with polymeric addition agents; (c) treating the base matrix under pyrolysis conditions at an increased temperature in an atmosphere containing essentially no oxygen. The invention also relates to membranes that can be produced according to the aforementioned method, to flexible material that can be produced by using these membranes, and to their use for separating and purifying fluids.

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 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.
