Abstract (en)

[origin: WO2022122459A1] Disclosed is a method for the selective hydrogenation of a C2 steam-cracking fraction comprising acetylene, in the presence of a catalyst comprising an active phase made from at least one group VIII metal and a support in the form of a ceramic or metal monolith, characterised in that the support comprises a number of channels per unit length CPSI of between 300 and 1200, and in that the active phase is in the form of a layer on the walls of the support, the thickness of the active phase layer being between 30 µm and 150 µm.
