High Conversions of Light Olefinic Fractions into Gasoline and Middle Distillates

Oligomerization Catalysts

Oligomerization technologies achieve high conversions of light olefinic fractions into higher value gasoline and middle distillates in association with dedicated catalysts specially developed for these applications.

Heterogeneous Oligomerization

Olefins oligomerization to Gasoline and/or Middle Distillates

In a context of unbalanced gasoline/diesel slates worldwide, refiners aim to maximize middle distillates production by converting light olefins from LPG and gasoline into distillates. Long operating cycles are achieved due to specific high selectivity of the promoted alumina forming very low gums deposits on the active surface.

IP 811

IP 811 is used in light olefinic cuts oligomerization applications in general and in particular in the production of added value heavier olefinic cuts.

Homogeneous Oligomerization

C₃ or C₄ Olefins Dimerization

High-octane value motor gasoline is obtained from olefinic C3 cuts from FCC or steam-cracking. Oligomerization of C3 or C4 olefins produces with a high selectivity hexenes, heptenes and higher olefins up to dodecenes.
