Abstract: AN OLIGOMERIZATION CATALYST FOR OLEFINS HAVING FROM 2 TO 6 CARBON ATOMS IS PRODUCED BY TREATING ALUMINUM OXIDE WITH A NICKEL COMPOUND AND A SULFUR COMPOUND, EITHER SIMULTANEOUSLY OR FIRSTLY WITH THE NICKEL COMPOUND AND THEN WITH THE SULFUR COMPOUND, AND SUBSEQUENTLY DRYING AND CALCINING THE RESULTING CATALYST, WHEREIN A MOLAR RATIO OF SULFUR TO NICKEL IN THE FINISHED CATALYST OF FROM 0.25:1 TO 0.38: IS SET IN THIS WAY.THE CATALYST AND ITS USE ARE ALSO DESCRIBED.

Abstract: In the process for the selective hydrogenation of dienes in supply flows containing them, such a flow is hydrogenated on a nickel-containing precipitating catalyst at a temperature of between 40 and 100 DEG C, a pressure of between 3 and 20 bar and a WHSV (weight hourly space velocity) of between 1 and 10 kg/(lxh) in the presence of free hydrogen.
