  • Process for preparing a Ni/Sn supported catalyst for the selective hydrogenation of polyunsaturated hydrocarbons
    Patent number: 8637425
    Abstract: A process is described 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 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.

  • PROCESS FOR PREPARING A SUPPORTED CATALYST BASED ON Ni AND A METAL FROM GROUP IB, FOR THE SELECTIVE HYDROGENATION OF POLYUNSATURATED HYDROCARBONS
    Publication number: 20110160503
    Abstract: A process is described for preparing a catalyst comprising at least one porous support and at least one metallic phase containing nickel and at least one metal M from group IB in a proportion such that the molar ratio M/Ni is in the range 0.005 to 0.5, said process comprising at least the following steps in succession: a1) depositing nickel on at least said support in order to obtain a supported nickel-based monometallic catalyst; b1) depositing, in the presence of at least one reducing gas and in the absence of any aqueous solvent, at least one organometallic compound of at least said metal M onto said monometallic catalyst.
