Description
Summary:The hydrodeoxygenation (HDO) of 5-nonanonea model compound for more complex biomass-derived moleculesto n-nonane was investigated using a variety of heterogeneous multifunctional metal-impregnated aluminosilicate catalysts in a packed-bed continuous flow reactor system. Under optimized reaction conditions (200 °C, 1.38 MPa H2), >99% conversion and >99% selectivity to n-nonane was achieved within a 30 min residence time over both Ni (7 wt %) and Co (9 wt %) supported on Perlkat 79-3, a high-surface area amorphous aluminosilicate. This work provides a further understanding of the effects of different metals, supports, and metal loading amounts on HDO of 5-nonanone and demonstrates an efficient translation of HDO reactions of ketones from batch reactors to continuous flow systems.
