Abstract

A dismountable and dismantlable loading system for loading a reactor with bulk material, is described. The dismantlable rail system with a multiplicity of rail segments can be connected to one another to form a self-contained rail system, wherein the individual rail segments have the ability to connect the rail segments to one another. Also provided is at least one rail vehicle for operation on the rail system, having a holding device for containers for receiving the bulk material, and at least one filling station for receiving the bulk material, having a hose present in the floor of the filling station for transporting the bulk material into various areas of the reactor.

First claim

The invention claimed is:

1. A dismountable and dismantlable loading system for loading a reactor with bulk material, comprising:
(a) a dismantlable rail system with a multiplicity of rail segments which can be connected to one another to form a self-contained rail system, wherein the individual rail segments are attachable, thereby connecting the rail segments to one another,
(b) at least one rail vehicle for operation on the rail system having a holding device for containers for receiving the bulk material, and
(c) at least one filling station for receiving the bulk material, having a hose present in the floor of the filling station for transporting the bulk material into various areas of the reactor.

2. The loading system as claimed in claim 1 , wherein the rail segments have markings for assembling the rail system.

3. The loading system as claimed in claim 1 , wherein the cross section of the hose is compressible.

4. The loading system as claimed in claim 1 , wherein the hose has a length of at least 1 m.

5. The loading system as claimed in claim 1 , wherein the hose is releasably attached to the filling stations.

6. The loading system as claimed in claim 1 , wherein the hose has a diameter in the range of 30 to 80 mm.

7. The loading system as claimed in claim 1 , wherein the the rail segments each have a cross section in the dismantled state that amounts to at most 100 cm.

8. The loading system as claimed in claim 1 , wherein the filling stations each have a device for securing them in the reactor.

9. The loading system as claimed in claim 1 , wherein the containers for receiving the bulk material have hoses in a floor of the container for transporting the bulk material to the filling stations.

10. The loading system as claimed in claim 1 , wherein a multiplicity of rail vehicles for simultaneous operation on the rail system are present.

11. A method for loading a reactor with bulk material, wherein the reactor has a lower and an upper reactor area, using a loading system as claimed in claim 1 , having the following method steps:
(A) introducing the dismantled constituent parts of the loading system into the reactor,
(B) mounting the rail system in the reactor as a self-contained rail system running around the center of the reactor in the upper area of the reactor, and mounting the at least one filling station adjacent to the rail system,
(C) introducing the bulk material into the reactor and transporting the containers having the bulk material on the rail system to the at least one filling station by way of the at least one rail vehicle,
(D) transferring the bulk material from the containers to the at least one filling station and filling the reactor by conveying the bulk material into the lower reactor area via hoses, and,
(E) if necessary, dismounting and dismantling the loading system and transporting the dismantled constituent parts out of the reactor.

12. The method as claimed in claim 11 , wherein the loading system comprises a multiplicity of containers and a multiplicity of filling stations, and markings for respectively identifying a filling station and at least one container assigned to the filling station are present on the multiplicity of containers and the multiplicity of filling stations, and wherein, in method steps (C) and (D), a container assigned to a certain filling station is transported to this filling station via the rail system, and the bulk material is poured into this filling station.

13. The method as claimed in claim 12 , wherein, in method step (D), a plurality of containers are assigned to a filling station and wherein, toward the end of the filling operation, the hose is removed from the filling station.

14. The method as claimed in claim 12 , wherein the reactor has involute channels in its upper area, and the bulk material is introduced between the channels into the reactor from the filling stations through the hoses in method step (D).

15. The method as claimed in claim 12 , wherein the upper area of the reactor has a manhole with an opening cross section, and the dismantled constituent parts of the loading system are brought into the reactor through the manhole in method step (A), wherein the constituent parts of the system, in particular the rail segments, each have a cross section in the dismantled state which is smaller than the opening cross section of the manhole.

16. The method as claimed in claim 12 , wherein a multiplicity of rail vehicles are present and in method steps (C) and (D) the bulk material is continuously introduced into the reactor by means of a multiplicity of containers and distributed in the filling stations via the rail vehicles.

17. The method as claimed in claim 12 , wherein the bulk material used is catalyst material.

18. The method as claimed in claim 17 , wherein the catalyst material is in the form of pellets.

19. The loading system as claimed in claim 1 , wherein the hose has a length of at least 2 m.

20. The loading system as claimed in claim 1 , wherein the rail segments each have a cross section in the dismantled state that amounts to at most 80 cm.
