Device useful for hydrogenation reactions (III)

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.
