Process for the preparation of a catalyst based on a Group VIII metal and containing silicon, and a process for selective hydrogenation carrying out said catalyst

摘要

A method for preparing a selective hydrogenation catalyst is provided, comprising a catalyst precursor comprising at least one Group VIII metal in the form of a metal and at least one support comprising at least one oxide. Wherein the catalyst precursor in the metal form contains a silicon compound in the presence of a liquid phase and a reducing and / or inert atmosphere. Characterized in that it is contacted with a non-polar solvent; said silicon compound is selected from silanes, silanols and cyclic siloxanes containing at least one Si-H bond and at least one Si-C bond It is. A selective hydrogenation process using the catalyst is also described.
