摘要:
A particulate selective hydrogenation catalyst for transforming unsaturated diolefinic hydrocarbons to .alpha.-olefinic hydrocarbons is described, for the hydrogenation of diolefinic compounds to .alpha.-olefinic compounds at rates which are at least 1.5 times higher than the rate of hydrogenation of .alpha.-olefinic hydrocarbons to saturated compounds. The catalyst contains palladium distributed at the periphery of particles (spherules or extrudates), and at least one element selected from tin and lead. Further, the tin and/or lead is advantageously distributed at the periphery of the spherules or extrudates. The catalyst preparation is also described, as well as a process for selective hydrogenation of diolefins to .alpha.-olefins using the catalyst.
