Glucose was decomposed at 350 degrees C within a dilute H-2 environment in the presence of monometallic, deoxygenation catalysts to promote in situ deoxygenation. The catalysts, which were supported on SiO2, included Ni, Cu, Co, and Fe in concentrations of 0.5 wt% and 4 wt% as well as Re, Pt, and Pd in concentrations of 0.5 wt%. Furanic compounds were used to identify deoxygenation due to their unique structures which allow them to be readily identified and because of their well-established deoxygenation reaction pathways. The 4% Co catalyst was deemed most superior at in situ deoxygenation. Ni catalysts were competitive in deoxygenation and helped reduce solid residue most substantially. 0.5 wt% catalysts reduced solid content the most however higher concentrations were needed for better in situ deoxygenation.
