Beschreibung
Zusammenfassung:	The present invention relates to a method for preparing a Ni/Sn support catalyst for selective hydrogenation of polyunsaturated hydrocarbons. Described is a method of preparing a catalyst, the catalyst comprises at least one porous support and at least one metallic phase containing nickel (Ni) and tin (Sn) in a proportion such that the molar ratio of Sn/Ni is 0.01-0.2, the method comprises: (a) depositing nickel on the support to obtain a monometallic supported catalyst made of nickel; (b) reducing the monometallic catalyst in the presence of at least one reducing gas; (c) depositing, in gas phase and in the presence of the reducing gas, at least an organometallic compound of tin on the reduced monometallic catalyst; and (d) activating the solid resulting from the step (c) in the presence of the reducing gas.
