Selective hydrogenation of diolefins in steam cracking petrol on catalysts based on a support metal in which an organic compound has been incorporated prior to loading into the reactor

摘要

The invention relates to a process for the selective hydrogenation of diolefins in steam cracking petrol in the presence of a nickel catalyst and is characterized in that prior to the use of the catalyst, a suphur- containing organic compound is incorporated into the catalyst outside of the reactor.
