Method and apparatus for determining a fraction of an adsorbed material contained in an adsorber material

摘要

A method for determining a fraction of an adsorbed material contained in a formed body serving as an adsorber material. For the case in which the adsorber material is present in the form of a formed body, at least two electrodes are arranged, spaced apart from one another, on a surface of the formed body and/or are firmly inserted in the formed body; that, for the case, in which the adsorber material is present in the form of a powder or granulate, a corresponding formed body made of the same material is durably inserted in the powder or granular material. The electrodes are supplied with an alternating electrical current, whereby an electrical characteristic variable is ascertained; and, based on the characteristic variable, degree of saturation of the adsorber material is ascertained. Furthermore, a corresponding apparatus is claimed.

1. A method for determining a fraction of an adsorbed material, which is located in a container in the form of a granular material or powder of zeolite, a zeolite composition or silica gel serving as adsorber material, comprising the steps of:
producing a formed body from the same material as the adsorber material and providing, at least two electrodes which form a capacitor, spaced apart from one another, on a surface of the formed body and/or firmly inserted in the formed body, and the formed body is durably inserted in the powder or granular material; supplying the electrodes with an alternating electrical current, whereby capacitance and/or loss factor tan δ are/is ascertained as the electrical characteristic variable of the adsorber material; and based on the ascertained electrical characteristic variable, the fraction of the adsorbed material in the adsorber material and degree of saturation of the adsorber material is ascertained.
