SELECTIVE HYDROGENATION OF ACETYLENES.

摘要

A process for removing acetylenic compounds using unsulfided metallic nickel or unsulfided metallic nickel modified with metallic Mo, Re, Bi or mixtures in which the catalyst is used alone or is used in combination with other acetylenic selective catalysts. The unsulfided metallic nickel catalyst or modified catalyst is preferably the first catalyst to contact the hydrocarbon stream.
