Selective Metathesis of alpha-Olefins from Bio-sourced Fischer-Tropsch Feeds


The search for a low-cost process for the valorization of linear alpha-olefins combining high productivity and high selectivity is a long-standing goal to chemists. Scientists from ISCR/OMC group (O. Baslé and M. Mauduit), in collaboration with IFP Energies nouvelles (H. Olivier-Bourbigou) and Salerno University/KAUST catalysis center (L. Cavallo) have reported a soluble ruthenium olefin metathesis catalyst that performs at low loadings (50 ppm) the conversion of linear alpha-olefins to longer internal linear olefins with high selectivity (>98%) under neat conditions and without the need of expensive additives. This robust catalytic process allowed to efficiently and selectively re-equilibrate the naphtha fraction (C5 to C8) of a Fischer-Tropsch feed derived from non petroleum resources to a higher value product range (C9 to C14), useful as detergent and plasticizer precursors. This work has been published in ACS Catalysis (2016, 6, 7970-7976) and is highlighted in the web site of INC.
