Figure 4: Predicted 3-dimentional changes of xylose concentration at different acid concentrations. (a) 1% (w/v) H2SO4 and 0.4% (w/v) H3PO4; (b) 2% (w/v) H2SO4 and 0.8% (w/v) H3PO4; (c) 2.5% (w/v) H2SO4 and 1% (w/v) H3PO4; (d) 3% (w/v) H2SO4 and 1.2% (w/v) H3PO4. Other assumed conditions: liquid to solid ratio 3 mL/g, 100–180°C.
