Abstract

The present invention relates to a device for treatment of material transported through the device comprising at least one porous element consisting of specific solid metallic structure which allows cross-flow of the material through the porous element and wherein the porous element is coated by a non-acidic metal oxide which is impregnated by palladium (Pd).

First claim

The invention claimed is:

1. A device for treatment of material transported through the device comprising at least one porous element which allows cross-flow of the material through the device, wherein
the at least one porous element consists of a solid metallic structure which is coated by a non-acidic metal oxide layer impregnated with Pd-nanoparticles having an average particle size of between 0.5 and 20 nm, and wherein
the at least one porous element is formed of a metal alloy comprising:
(i) 55 wt-%—80 wt-%, based on total weight of the metal alloy, of Co,
(ii) 20 wt-%—40 wt-%, based on total weight of the metal alloy, of Cr, and
(iii) 2 wt-%—10 wt-%, based on total weight of the metal alloy, of Mo.

2. The device according to claim 1 , wherein the metal alloy further comprises at least one metal selected from the group consisting of Cu, Fe, Ni, Mn, Si, Ti, Al and Nb.

3. The device according to claim 1 , wherein the metal alloy comprises:
(i) 55 wt-%—70 wt-%, based on total weight of the metal alloy, of Co,
(ii) 20 wt-%—35 wt-%, based on total weight of the metal alloy, of Cr, and
(i) 4 wt-%—10 wt-%, based on total weight of the metal alloy, of Mo.

4. The device according to claim 1 , wherein the non-acidic metal oxide layer which coats the at least one porous element is basic or amphoteric.

5. The device according to claim 1 , wherein the non-acidic oxide layer comprises ZnO and optionally at least one further oxide of a metal selected from the group consisting of Cr, Mn, Mg, Cu and Al.

6. The device according to claim 1 , wherein the non-acidic metal oxide layer comprises ZnO and Al 2 O 3 .

7. The device according to claim 1 , wherein the Pd-nanoparticles have an average particle size of between 2 and 15 nm.

8. The device according to claim 5 , wherein the non-acidic metal oxide layer comprises ZnO in an amount between 0.001 and 2 wt-%, based on the total weight of the non-acidic metal oxide layer.

9. The device according to claim 1 , wherein the Pd-nanoparticles are present in an amount between 0.0001 and 1 wt-%, based on total weight of the device.

10. The device according to claim 1 , wherein the at least one porous element comprises substantially sphere-shaped hollow spaces having an average equivalent diameter of 0.5 to 20 mm.

11. The device according to claim 1 , wherein the Pd nanoparticles have an average particle size of between 5 and 12 nm.

12. The device according to claim 1 , wherein the Pd nanoparticles have an average particle size of between 7 and 10 nm.

13. The device according to claim 10 , wherein the sphere shaped hollow spaces of the at least one porous element have an average equivalent diameter of 1 to 10 mm.

14. The device according to claim 10 , wherein the sphere shaped hollow spaces of the at least one porous element have an average equivalent diameter of 1.5 to 5 mm.
