Abstract

The present invention relates to a device for treatment of material transported through the device having a specific design.

First claim

The invention claimed is:

1. A reactor tube comprising:
an inlet end and an outlet end for treating a fluid flowing through the reactor tube between the inlet and outlet ends,
a plurality of grid structures arranged in series in a flow direction in the reactor tube for mixing the fluid flowing through the reactor tube between the inlet and outlet ends, wherein
each of the grid structures consists of three sets of parallel partitions which bound flow channels with a flow cross section in the form of a regular polygon, and wherein
the three sets of partitions of adjacent grid structures are rotated with respect to one another by an angle of 60 degrees with an orientation of the grid structures being repeated periodically.

2. The reactor tube according to claim 1 , wherein adjacent partitions in each set of the parallel partitions are equally spaced.

3. The reactor tube according to claim 1 , wherein the three sets of parallel partitions intersect at an angle of 120 degrees, and wherein the partitions bound flow channels with a flow cross section in the form of an equilateral triangle.

4. The reactor tube according to claim 3 , wherein the length of the grid structures in the flow direction approximately corresponds to a side length of the equilateral triangles.

5. The reactor tube according to claim 3 , wherein the equilateral triangle has a height from 1-10 mm.

6. The reactor tube according to claim 5 , wherein the three sets of parallel partitions have a periodic unit length of 3-30 mm, and wherein the periodic unit length is 3 times the height of the equilateral triangle.

7. The reactor tube according to claim 1 , wherein the three sets of partitions of adjacent grid structures are offset with respect to one another in a direction perpendicular to a plane of one of the partitions.

8. The reactor tube according to claim 1 , wherein the orientation of the grid structures repeats after three grid structures.

9. The reactor tube according to claim 1 , wherein two out of the three grid structures are arranged in series, and wherein a central axis of the reactor tube runs through an intersection line of the two partitions, and wherein an intersection line of a third grid structure it runs through the middle of one of the polygons.

10. The reactor tube according to claim 1 , wherein the grid structures are coated with an oxide primer layer and a catalyst layer.

11. The reactor tube according to claim 10 , wherein the primer layer is a mixed oxide comprising cerium oxide and zinc oxide.

12. The reactor tube according to claim 10 , wherein the catalyst layer comprises palladium nanoparticles.

13. A hydrogenation reactor which comprises a plurality of the reactor tubes according to claim 1 .
