Abstract

PURPOSE: A 4C hydrocarbon mixture resulting from steam cracking is previously washed with water and acetylenes and dienes in the mixture is hydrogenated in the presence of a palladium catalyst to prevent the activity reduction of the palladium catalyst for a long period of time.
CONSTITUTION: A hydrocarbon mixture mainly consisting of 4C hydrocarbons, resulting from steam cracking of hydrocarbons, is previously washed with water and acetylenes and dienes in the mixture is selectively hydrogenated in the presence of a palladium catalyst. Thus, selective hydrogenation is stably effected without reduction in the catalyst activity for a long period of time. As the palladium catalyst, is used preferably the one made by supporting 0.005W5% palladium on a carrier.
