Two-step process for converting light olefins into diesel-range hydrocarbons
09 July 2012
Researchers from Institut Charles Gerhardt (France) report the development of an original two-step process for converting light olefins into long-chain hydrocarbons in the distillate range. Their paper is published in the journal ChemSusChem.
In the first step, ethylene is selectively transformed into C4–C10 olefins with an even number of carbon atoms, over nickel-exchanged AlMCM-41, at 150 °C.
When the nickel-catalyzed oligomerization was assisted by a second acid-catalyzed step over H-MCM-41, olefins with chains longer than 10 carbon atoms were mainly produced with a productivity of 180 g g−1 h−1.
