Abstract:
A process for the selective hydrogenation of dienes in diene-containing feed streams, which comprises hydrogenating such a diene-containing feed stream over a nickel-containing precipitated catalyst at from 40 to 100.degree. C., a pressure of from 3 to 20 bar and a WHSV of from 1 to 10 kg/(l.times.h) in the presence of free hydrogen, wherein the catalyst comprises from 65 to 80% of nickel, from 10 to 25% of silicon, from 2 to 10% of zirconium, from 0 to 10% of aluminum, all components calculated as oxides and percentages by weight based on the total mass of the catalyst, with the proviso that the sum of the content of silicon dioxide and aluminum oxide is at least 15%.
