A PROCESS FOR PREPARING A SULPHIDED METALLIC SUPPORT CATALYST

摘要

A process for preparing a partly sulphided metallic supported catalyst is described with especially uniform distribution of sulphur by contacting the catalyst either during or after precipitation with flowers of sulphur in aqueous medium at pH 7 to 11. The atomic ratio of sulphur to nickel at the surface of the nickel is preferably from 0.33 to 0.70 for hydrogenation of unsaturated fatty acid derivatives.
