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. The invention also relates to a device for carrying out the inventive method.
