摘要 |
The invention relates to a process of reduction of a refining catalyst before its use, the catalyst containing a support and an active phase with a base of at least one noble or nonnoble metal of Group VIII or Group Ib of the periodic table, the process consisting in: a) impregnating the catalyst with an aqueous or organic solution of a reducing agent compound, b) breaking down the reducing agent compound by heating the catalyst; c) drying the catalyst thus obtained. The invention is characterized in that a halogen additive is added with the reducing agent. The catalyst thus treated is particularly suitable, for example, for selective hydrogenation of unsaturated hydrocarbons.
