CSU team reports tandem process for converting furaldehydes into oxygenated diesel and linear alkane fuels
Researchers at Colorado State University report using a tandem process to upgrade biomass furaldehydes into oxygenated diesel and high-quality C10–12 linear alkane fuels. A paper on their work is published in the journal ChemSusChem.
The first of the two steps involves solvent-free self-condensation through organocatalysis using an N-heterocyclic carbene (NHC), yielding C10–C12 furoin intermediates.
In the second, tandem metal–acid catalysis step, in water, the furoin intermediates are converted into oxygenated biodiesel by hydrogenation, etherification or esterification; or into premium alkane jet fuels by hydrodeoxygenation.
