Abstract (en)

[origin: WO2020148131A1] The invention relates to a process for preparing a selective hydrogenation catalyst comprising nickel, copper and a support having at least one refractory oxide, said process comprising the following steps: - contacting the support with a solution containing at least one copper precursor and a nickel precursor; - drying the catalyst precursor at a temperature of less than 250°C; - reduction of the catalyst precursor by contacting said precursor with a reduction gas at a temperature of between 150°C and 250°C; - contacting the catalyst precursor with a solution comprising a nickel precursor; - step of drying the catalyst precursor at a temperature of less than 250°C; - reduction of the catalyst precursor by contacting said precursor with a reduction gas at a temperature of between 150°C and 250°C.
