Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:

[0042] FIG. 1 shows a block diagram of a process for manufacturing an MMO according to the present disclosure; and

[0043] FIG. 2 schematically shows an example of a motor vehicle which has a device for capturing atmospheric air according to the present disclosure.

DETAILED DESCRIPTION

[0044] FIG. 1 shows an example of a process 1 for manufacturing an MMO (or a material in general, as described below) according to the present disclosure.

[0045] In 2, a material is used that has a core and terminal primary amine end groups, which in this embodiment includes manufacturing a layered MMO as described herein.

[0046] In 3, the primary amine end groups of the material are capped epoxy-based, as described herein.

[0047] FIG. 2 shows an embodiment of a motor vehicle 10 according to the present disclosure. The motor vehicle 10 comprises a device 11 which comprises a material for absorbing carbon dioxide according to the present disclosure. In this embodiment, the device 11 is provided in an intake line of a motor vehicle.

[0048] Some examples relate to a process for manufacturing a material for absorbing carbon dioxide from atmospheric air, comprising: using a material with a core and with terminal primary amine end groups; and epoxy-based end capping of the terminal primary amine end groups to give secondary amine end groups, as described herein.

[0049] Use may also include manufacture.

[0050] In some examples, the epoxy can include ethylene oxide and/or propylene oxide, as described herein.

[0051] In some examples, the core can include an MMO or activated carbon. In some embodiments, the MMO includes an MMO PEI.

[0052] It has been recognized that activated carbon has different thermal conductivity than, for example, an MMO. Activated carbon can warm up faster and cool faster, so there may not be a need to desorb at such high [sic-levels?] when using activated carbon.

[0053] Overall, activated carbon as a core has a better energy balance than known materials. Furthermore, it was recognized that activated carbon could be pretreated in an alkaline or acidic way, so that aging properties could be further improved, as an intermolecular interaction between activated carbon and (for example) polyethyleneimine can be improved with regard to aging.

[0054] In some examples, the MMO includes Mg.sub.nAlCO.sub.3, wherein n is indicative of a molar ratio of Mg and Al, as described herein.

[0055] Some examples relate to a material for absorbing carbon dioxide from atmospheric air which has terminal secondary amines, as described herein. In some embodiments, the terminal secondary amines are bound to epoxy attached to a core, as described herein. In some embodiments, the epoxy includes ethylene oxide and/or propylene oxide.

[0056] Some examples include a device for capturing carbon dioxide from atmospheric air, comprising a substance for capturing carbon dioxide as described herein.

[0057] Some examples relate to a motor vehicle, including a device for capturing carbon dioxide from atmospheric air, as described herein.

[0058] The MMO's applications for absorbing CO.sub.2 from atmospheric air are also applicable to the more general substance, as described herein, which can also include, for example, activated carbon, which is why a repetitive description of the above explanations is omitted at this point.

[0059] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
