Figure 1.
Effect of NaHCO3 addition on hydrothermal treatment of PN and SB. Reaction conditions: 20.0 g/L biomass, 250 °C, 30 min. Bars (left axis) represent yields: (gray bars): FA, (black bars): AA, and (clear bars): LA. Symbols (right axis): (cross): total yield of liquefied matter, %Yorganic, and (diamonds): selectivity of the identified acids, %Sacids, both expressed in mol of carbon. The rest of the dissolved organics are mostly sugars.
