Process for preparing a supported metal catalyst and selective hydrogenation process using such a catalyst

摘要

A process for preparing a supported metal catalyst based on Pd and Cu for the selective hydrogenation of polyunsaturated hydrocarbons comprises, in cascade, the steps of impregnating a porous support with a solution of a palladium and potassium salt, submitting the resulting solid product to a hydrogen flowing stream, impregnating the resulting solid material with a copper salt solution, submitting the resulting solid product to a flowing hydrogen stream, and drying the resulting solid product.
