摘要
The aqueous-phase processing (APP) of the biomass-derived bio-oil model compounds, hydroxyacetone, propylene glycol, 1-propanol, 2-propanol, propanoic acid, and acetone, over Pt-Re/C were explored. For the APP of hydroxyacetone at 250 degrees C, the product distribution was determined and quantified. Propylene glycol, 1-propanol, propanoic acid, ethanol, acetic acid, CO2, H-2, CH4, C2H6 and C3H8 were found to be primary products with 2-propanol, acetone and CO as minor products. By also exploring the product distributions of propylene glycol, 1-propanol, 2-propanol, propanoic acid, and acetone under the same APP conditions, a reaction network associated with the APP conversion of hydroxyacetone was determined. Using this reaction network, flux analysis was performed on the hydroxyacetone reaction system to confirm the reaction pathway and relative rates (nu(1)-nu(12)) for each step. From this analysis, it was found that the hydrogenation/dehydration of hydroxyacetone was the most rapid reaction in the reaction system.
