Abstract:
1. A process for preparing a catalyst comprising at least one porous support and at least one metallic phase containing nickel and tin in a proportion such that the Sn/Ni molar ratio is in the range of 0.01 to 0.2, said process comprising at least the following steps in succession: a) depositing nickel on at least said support in order to obtain a supported nickel-based monometallic catalyst; b) reducing said monometallic catalyst in the presence of at least one reducing gas; c) depositing, in the gas phase and in the presence of at least one reducing gas, at least one organometallic tin compound onto said reduced monometallic catalyst; and d) activating the solid derived from said step c) in the presence of at least one reducing gas in order to obtain a supported catalyst having a metallic phase based on nickel and tin in which the tin represents 0.02% to 15% by weight of the mass of said catalyst and the nickel represents 1% to 50% by weight of the mass of said catalyst with an Sn/Ni molar ratio in the range of 0.01 to 0.2.
