The freight container according to the invention offers the advantage that, by providing at least one intermediate fitting according to ISO 1161 or a pair of intermediate fittings, defined load-bearing points are provided for, for example, various units that must be attached to the outer wall/outside of the freight container. On the other hand, it is possible, if necessary using appropriate support elements such as posts, to stack ISO freight containers of different sizes on top of one another and/or to stack several small ISO freight containers next to one another on a larger ISO freight container. The freight container according to the invention can advantageously also be manufactured automatically using simple mass production on container production lines.

The freight container according to the invention can also advantageously be used or employed in an adsorption chamber module and/or a CO2 adsorption device as a chamber module housing for accommodating an adsorbent for adsorbing the CO2 from the supplied air flow. The intermediate fittings or pairs of intermediate fittings can be used to connect partition walls in the interior of the freight container in order to provide vacuum-stable chambers for the desorption process.

In the context of the present invention, the terms "connected" or "connecting" preferably mean a material connection. The (ISO) freight container or shipping container according to the invention is designed according to ISO 668. The freight container or ISO freight container has a basic frame and corner fittings according to ISO 1161. The corner fittings are attached to all container corners or basic frame corners are firmly bonded to the basic frame. The freight container also has at least one intermediate fitting in accordance with ISO 1161 or at least one pair of intermediate fittings made up of two intermediate fittings in accordance with ISO 1161 that are connected to one another, in particular firmly bonded, which is/are firmly bonded to the basic frame.

The basic frame preferably has - similar to standard ISO freight containers - two longitudinal end frames, each of which has a corner fitting arranged at its four corners. The end frames can each have a roof cross member, a floor cross member and two corner posts. The basic frame preferably also has two roof longitudinal members and two floor longitudinal members, which connect the two longitudinal end frames to one another at their corner fittings. The basic frame can also have further floor cross members, which connect the two floor longitudinal members to one another along their longitudinal direction and stiffen a floor of the basic frame or the freight container.

The at least one intermediate fitting or the at least one pair of intermediate fittings is arranged between two corner fittings. The at least one intermediate fitting or the at least one pair of intermediate fittings is preferably arranged within the external dimensions or dimensions of the ISO freight container.

The intermediate fitting or the pair of intermediate fittings is connected to the basic structure, i.e. mechanically and in particular materially connected. In this case, the at least one intermediate fitting or the at least one pair of intermediate fittings is preferably connected to a roof longitudinal member or a floor longitudinal member of the basic structure. Further preferably, the at least one intermediate fitting or the at least one pair of intermediate fittings is arranged along a longitudinal direction of the roof longitudinal member or the floor longitudinal member in the roof longitudinal member or the floor longitudinal member. The at least one intermediate fitting or the at least one pair of intermediate fittings can, for example, be arranged between two roof longitudinal member elements of the roof longitudinal member or between two floor longitudinal member elements of the floor longitudinal member and connected to these on opposite sides. Accordingly, the intermediate fitting or the pair of intermediate fittings is preferably arranged directly on the basic frame or the roof longitudinal member or the floor longitudinal member and is directly connected to it.

In this case, the at least one intermediate fitting or the at least one pair of intermediate fittings of the roof longitudinal member can be arranged in a vertical direction of the freight container above the corner fittings of the roof longitudinal member. Alternatively or additionally, the at least one intermediate fitting or the at least one pair of intermediate fittings of the floor longitudinal member can be arranged in a vertical direction of the freight container above the corner fittings of the floor longitudinal member, so that the freight container can be easily placed on an uneven floor without sitting on it in the middle. The distance between the intermediate fittings or

Intermediate fitting pairs for the respective corner fittings can be in a vertical direction, for example, in a range of greater than or equal to 10 mm to less than or equal to 45 mm. The intermediate fittings or

However, intermediate fitting pairs are arranged vertically essentially at the same height as the corner fittings.

Preferably, at least two intermediate fittings or intermediate fitting pairs are provided, of which one intermediate fitting or intermediate fitting pair is connected to the roof longitudinal member and another intermediate fitting or another intermediate fitting pair is connected to the floor longitudinal member of the same container longitudinal side. The two intermediate fittings or intermediate fitting pairs are preferably arranged essentially flush one above the other in a vertical direction of the freight container.

Preferably, at least one intermediate post is provided which connects the two intermediate fittings or pairs of intermediate fittings to one another. The intermediate post can be constructed analogously to a corner post. In other words, an intermediate post preferably connects an intermediate fitting or pair of intermediate fittings of the floor longitudinal member with an intermediate fitting pair of the roof longitudinal member arranged above it. In the case of intermediate fitting pairs, the intermediate post can be formed from two posts connected to one another, in particular corner posts.

Advantageously, two further intermediate fittings or pairs of intermediate fittings can be provided, which are arranged on the roof longitudinal member and the floor longitudinal member of an opposite longitudinal side of the container and are connected to one another by means of at least one further intermediate post. The two intermediate fittings or pairs of intermediate fittings of the roof longitudinal members and the two intermediate fittings or pairs of intermediate fittings of the floor longitudinal members are preferably arranged substantially flush with one another in a transverse direction of the freight container.

It is advantageous if at least one intermediate roof cross member is provided which connects the two intermediate fittings or pairs of intermediate fittings of the longitudinal roof members to one another. The intermediate roof cross member can be constructed in a similar way to a roof cross member of the end frame. In the case of pairs of intermediate fittings, the intermediate roof cross member can be formed from two cross members connected to one another, in particular roof cross members.

It is also advantageous if at least one intermediate floor cross member is provided, which connects the two intermediate fittings or pairs of intermediate fittings of the longitudinal floor members to one another. The intermediate floor cross member can be constructed in a similar way to a floor cross member of the end frame. In the case of pairs of intermediate fittings, the intermediate floor cross member can be formed from two interconnected cross members, in particular floor cross members.

In this case, the four interconnected intermediate fittings or pairs of intermediate fittings, the at least two intermediate posts, the at least one intermediate roof cross member and, if applicable, the at least one intermediate floor cross member can at least preferably form an intermediate frame. The intermediate frame can in particular be designed analogously to one or two interconnected longitudinal end frames of the basic framework. In this way, longitudinal end frames can advantageously Basic frames for freight containers can be manufactured inexpensively in accordance with ISO 668 as standard and can be installed or used multiple times in the previously described design, e.g. by welding.

Advantageously, at least one or exactly one further intermediate frame is provided. However, it can also be advantageous if exactly two, exactly three or exactly four further intermediate frames are provided.

Accordingly, a total of exactly one, exactly two, exactly three, exactly four or exactly five intermediate frames is preferably provided.

In a preferred embodiment, a partition wall is arranged on at least one, in particular on exactly one, exactly two, exactly three, exactly four or exactly five of the intermediate frames, which partition wall is connected to the respective intermediate frame and divides an interior of the freight container into separate chambers.

The partition wall can preferably comprise two interconnected corrugated sheet elements or trapezoidal sheet elements. In particular,

- wave crests of one corrugated sheet element are connected to wave troughs of the other corrugated sheet element or trapezoidal crests of one trapezoidal sheet element are connected to trapezoidal valleys of the other trapezoidal sheet element, or

- The ribs of one corrugated sheet element or trapezoidal sheet element form an angle of substantially 90° to the ribs of the other corrugated sheet element or trapezoidal sheet element.

This measure makes it possible to provide several separate chambers with rigid walls, which can be used as adsorption-desorption chambers in a CO2 adsorption device for separating CO2 from a supplied air stream, for example. The pressure-resistant design is essential here, since high forces act on the chamber walls during the desorption process due to the negative pressure in the chambers.

Preferably, the intermediate fittings or the intermediate fitting pairs, in particular the intermediate frame or frames, have such a distance from the corner fittings, in particular one of the longitudinal end frames of the basic structure such that a shorter freight container and/or several shorter freight containers according to ISO 668 can be stacked on the freight container. In other words, the intermediate fittings or the pairs of intermediate fittings or the intermediate frame(s) in the longitudinal direction of the freight container have a grid dimension of preferably essentially 8 feet, 10 feet, 20 feet, 40 feet or 45 feet to the corner fittings or one of the longitudinal end frames. This means that ISO freight containers of different sizes can be stacked on top of one another and/or several small ISO freight containers can be stacked next to one another on a larger ISO freight container.

The freight container preferably has - analogous to standard ISO freight containers - a base plate as well as a roof plate and side walls, in particular made of corrugated iron or trapezoidal sheet metal.

When manufacturing the freight container, at least one intermediate frame is first formed or manufactured using the four intermediate fittings or pairs of intermediate fittings, the at least two intermediate posts, the at least one intermediate roof cross member and, if applicable, the at least one intermediate floor cross member. A standard process for manufacturing the longitudinal end frames of basic frames of freight containers in accordance with ISO 668 can preferably be used here. The finished intermediate frame or two of the intermediate fittings or pairs of intermediate fittings of the finished intermediate frame are then connected to two longitudinal floor members of the basic frame. A standard process for manufacturing basic frames of freight containers in accordance with ISO 668 can also be used here.

Preferably, in the step of connecting, the two intermediate fittings or intermediate fitting pairs of the intermediate frame are first connected to a longitudinal end of two floor longitudinal beam elements and then to a longitudinal end of two further floor longitudinal beam elements on one or their opposite side, so that the two intermediate fittings or intermediate fitting pairs are arranged along a longitudinal direction of the respective floor longitudinal beam in the floor longitudinal beam between the floor longitudinal beam elements. The CO2 adsorption device according to the invention is designed or configured to separate CO2 from a supplied air stream by means of an adsorption-desorption process, i.e. a cyclically carried out or performed adsorption-desorption process. The basic functioning of the CO2 adsorption device or of the cyclically carried out or performed adsorption-desorption process can, for example, be carried out analogously to WO 2020/212146 A1 mentioned at the beginning. For this purpose, the CO2 adsorption device has an adsorption chamber module according to the invention and at least one fan unit for supplying the air stream via the inlet channel into the adsorption-desorption chamber and/or at least one temperature control unit for temperature control of the adsorbent for the adsorption-desorption process and/or at least one pump unit for providing an overpressure and/or negative pressure for the desorption process.

In the context of the present invention, the term “supply” or “supplied” includes an actively carried out or initiated and thus technically controlled or regulated supply of the air flow by means of a fan unit.

The adsorption chamber module according to the invention is designed or configured to separate CO2 from a supplied air stream in the CO2 adsorption device by means of an adsorption-desorption process.

For this purpose, the adsorption chamber module has a previously described freight container according to the invention, which functions as a chamber module housing.

In the adsorption-desorption chamber, an (appropriately functionalized) adsorbent for adsorption, ie for Binding or filtering of the CO2 from the supplied air stream, e.g. in the form of CO2 adsorption modules.

The adsorption chamber module further comprises an inlet channel for supplying the air flow into the adsorption-desorption chamber and an outlet channel for discharging the CO2-reduced air flow from the adsorption-desorption chamber. The inlet channel and the outlet channel are preferably arranged in the freight container, i.e. within the external dimensions of the freight container.

In a preferred embodiment, the separate chambers in the interior of the freight container are each designed as adsorption-desorption chambers, each with an inlet channel for supplying the air flow into the respective adsorption-desorption chamber and an outlet channel for discharging the CO2-reduced air flow from the respective adsorption-desorption chamber. In other words, the partition walls arranged and attached to the intermediate frames in the freight container form several adsorption-desorption chambers, which can be used in parallel and/or one after the other for adsorption and/or desorption.

An adsorbent is preferably arranged in the adsorption-desorption chamber or the adsorption-desorption chambers.

Fig. 3 is a flow chart of a method for producing a freight container according to the invention.

Fig. 1 shows an adsorption chamber module according to the invention, which is provided in its entirety with the reference number 10. The adsorption chamber module 10 is designed to be used in a CO2 adsorption device (not shown) for separating CO2 from a supplied air stream by means of an adsorption-desorption process.

For this purpose, the adsorption chamber module 10 has a freight container 12 according to the invention, which functions as a chamber module housing 12.

The freight container 12 is designed according to ISO 668 and has a length of 40 feet. The freight container 12 also has a basic frame 14.

The basic frame 14 has - analogous to standard ISO freight containers - two longitudinal end frames 16, at the corners of which a corner fitting 18 according to ISO 1161 is arranged and is integrally connected to the basic frame 14. The end frames 16 also each have a roof cross member 20, a floor cross member 22 and two corner posts 24, which connect the four corner fittings 18 to one another. The basic frame 14 also has two roof longitudinal members 26 and two floor longitudinal members 28, which connect the two longitudinal end frames 16 to one another at their corner fittings 18. The basic frame can also have further floor cross members, which connect the two floor longitudinal members 28 to one another along a longitudinal direction 30 of the freight container 12 and stiffen a floor 32 of the basic frame 14 or of the freight container 12.

According to the invention, the freight container 12 has intermediate fitting pairs 34, each of which has two intermediate fittings 36 according to ISO 1161 that are connected to one another in a materially bonded manner. The intermediate fitting pairs 34 are connected in a materially bonded manner to the basic frame 14 or the roof longitudinal members 26 and the floor longitudinal members 28 of the basic frame 14. The intermediate fitting pairs 34 are each arranged between roof longitudinal member elements 26a of the roof longitudinal members 26 or floor longitudinal member elements 28a of the floor longitudinal members 28 and are connected in a materially bonded manner to their ends.

On each longitudinal member 26, 28, three intermediate fitting pairs 24 are arranged evenly along the longitudinal direction 30. As a result, intermediate fitting pairs 34 of the roof longitudinal members 26 and intermediate fitting pairs 34 of the floor longitudinal members 28 are of the same Container long sides are arranged one above the other in a vertical direction 38 of the freight container 12. Furthermore, intermediate fitting pairs 34 of a roof longitudinal member 26 or floor longitudinal member 28 and intermediate fitting pairs 34 of the opposite roof longitudinal member 26 or floor longitudinal member 28 are each arranged in a transverse direction 40 of the freight container 12 in a flush manner.

The freight container 12 also has intermediate posts 42, with each intermediate post 42 connecting an intermediate fitting pair 34 of the floor longitudinal member 28 to the intermediate fitting pair 34 of the roof longitudinal member 26 arranged above it. The intermediate posts 42 each have two posts connected to one another, which are designed analogously to the corner posts 24 of the end frames 16.

The freight container 12 also has intermediate roof cross members 44, with each intermediate roof cross member 44 connecting two intermediate fitting pairs 34 of the longitudinal roof members 26. The intermediate roof cross members 44 each have two interconnected cross members, which are designed analogously to the roof cross members 20 of the end frames 16.

The freight container 12 further comprises intermediate floor cross members 46, wherein each intermediate floor cross member 46 connects two intermediate fitting pairs 34 of the longitudinal floor members 28. The intermediate floor cross members 46 each comprise two interconnected cross members which are designed analogously to the floor cross members 22 of the end frames 16.

Here, four interconnected intermediate fitting pairs 36, the two associated intermediate posts 42, the associated intermediate roof cross member 44 and the associated intermediate floor cross member 46 each form an intermediate frame 48. The intermediate frames 48 are designed analogously to two longitudinal end frames 16, which are connected to one another. In the embodiment shown, the freight container 12 has three intermediate frames 48, which are arranged equidistantly, ie at a distance of 10 feet from one another, between the corner fittings 18 and the end frames 16. As can be seen in more detail in the following Fig. 2, This allows several shorter ISO freight containers to be stacked in parallel on the freight container 12.

Furthermore, the freight container 12 has a partition wall 50 on each intermediate frame 48, which is connected to the respective intermediate frame 48 and divides an interior of the freight container 12 into separate chambers 54. The partition walls 50 have two interconnected trapezoidal sheet elements, in which trapezoidal peaks of one trapezoidal sheet element are connected to trapezoidal valleys of the other trapezoidal sheet element.

The separate chambers 54 are each designed as adsorption-desorption chambers 54 for receiving an adsorbent (not shown) for adsorbing the CO2 from the supplied air flow. For this purpose, each adsorption-desorption chamber 54 has an inlet channel (not shown) for supplying the air flow into the respective adsorption-desorption chamber 54 and an opposite outlet channel (not shown) for discharging the CO2-reduced air flow from the respective adsorption-desorption chamber 54.

Fig. 2 shows a side view of the 40-foot freight container 12 from Fig. 1, on which two smaller 20-foot freight containers 56 are stacked. This is made possible by the intermediate fitting pairs 34 or intermediate frames 48 and their corresponding design or arrangement. As can also be seen from Fig. 2, the intermediate fitting pairs 34 of the floor longitudinal members 28 are arranged in the vertical direction 38 of the freight container 12 above the corner fittings 18 of the floor longitudinal member 28, so that the freight container 12 can easily be placed on an uneven floor 58 without resting on it in the middle.

Fig. 3 shows a flow chart of a method 100 for producing a freight container 12. The method 100 comprises a step of forming 102 the at least one intermediate frame 48 by means of the four intermediate fittings 36 or intermediate fitting pairs 34, the at least two intermediate posts 42, the at least one intermediate roof cross member 44 and optionally the at least one intermediate floor cross member 46, in particular analogous to a standard method for manufacturing longitudinal end frames of basic frames of freight containers according to ISO 668. The method 100 further comprises a step of subsequently connecting 104 the intermediate frame 48, in particular two of the intermediate fittings 36 or intermediate fitting pairs 34 with two

Floor longitudinal beams 28 of the basic frame 14, in particular analogous to a standard method for producing basic frames of freight containers according to ISO 668. If an embodiment includes an “and/or” connection between a first feature and a second feature, this is to be read as meaning that the embodiment according to one embodiment has both the first feature and the second feature and according to another embodiment either only the first feature or only the second feature.
