Process for selectively hydrogenating a di-olefin in a mixture of hydrocarbons having at least 4 carbon atoms and comprising an alpha -olefin

摘要

Process for selectively hydrogenating a diolefin present in a mixture of hydrocarbons having at least 4 carbon atoms per molecule: the hydrocarbon mixture is reacted with hydrogen in contact with a catalyst comprising palladium and silver, the molar ratio of hydrogen to the diolefin being from 1:1 to 5:1.
