摘要:
The invention relates to a method for producing an adsorbent from organometallic framework structures (MOF), in which at least one metal salt is converted together with at least one organic ligand. The conversion occurs at a temperature of greater than 100 °C in a solvent mixture which contains DMSO and water. The invention further relates to an absorbent produced by means of the method according to the invention and to a substrate coated with such an absorbent and application possibilities of such an absorbent or substrate.

According to the invention, a method is provided for coating at least in areas a component with a layer of a metal-organic framework (MOF), in which the body is contacted with a solution containing at least one metal salt (MOF precursor), at least one linker, and at least one solvent. The linker in this case can effect the bonding of the MOF layer to the surface of the component and/or the structure of the MOF layer. The method is characterized in that the solution has a temperature gradient, wherein the temperature of the solution immediately at the surface of the component permits the crystallization of an MOF layer on the surface, whereas the temperature of the remaining solution prevents the formation of MOF crystals in the remaining solution. The method can be used for producing components having layers of defined chemical and/or physical properties. Furthermore, the invention comprises components which have at least in areas an MOF layer. A possible use of said components is in sorption refrigeration machines.

The invention relates to a heat exchanger (10) having at least one sorption duct (50) in which is arranged a sorption medium (5) and through which a fluid can be made to flow, characterized in that the heat exchanger also contains at least one catalyst (4) with which a fuel (45) can be converted exothermically such that at least some of the resulting heat (155) can be conveyed to the sorption medium (5). The invention also relates to a method for heating and/or conditioning a gas stream, having at least the following steps: supplying a gas stream, containing multiple different components, into a sorption duct (50) in which is arranged a sorption medium (5), such that at least one component (55) is bound in the sorption medium (5), and supplying and exothermically converting at least one fuel (45) under the action of a catalyst (4), such that at least one component (55) of the gas stream is expelled from the sorption medium (5).
摘要:
The invention relates to a dispersion and a method for coating objects, in particular heat-exchanger structures, in which this dispersion is applied to a support structure and is crosslinked and/or formed into a film, forming a layer. The invention likewise relates to heat-exchanger structures coated in this manner. The dispersions according to the invention can likewise be used for coatings in chemical installations construction and also in medical technology.
