Oligomerization of n -butenes over Ni/SiO 2 –Al 2 O 3 : influence of support modification by steam-treating

Fabian Nadolny, Ursula Bentrup, Nils Rockstroh, Felix Alscher et autres

The acidic properties of a selected SiO 2 –Al 2 O 3 support material have been modified by steam-treating to study the influence on the formation of active nickel sites for butene oligomerization.

Influence of Remaining Acid Sites of an Amorphous Aluminosilicate on the Oligomerization of n-Butenes after Impregnation with Nickel Ions

Fabian Nadolny, Felix Alscher, Stephan Peitz, Ekaterina S. Borovinskaya et autres

Highly linear octene isomers can be produced from n-butene on industrial scale by using Ni-containing aluminosilicates as heterogeneous catalysts. These catalysts can be prepared by impregnating an aluminosilicate with a Ni(II) salt solution. This leads to a competition between acid-catalyzed and nickel-catalyzed …
