Effect of severity parameter (logR 0 ) on the removal of xylan, lignin and cellulose. (a) Log R0 versus pH: solid triangles = water-only pretreatment; solid circles = 0.05% (w/w) H2SO4 pretreatment. (b) Log R0 versus removal of xylan, lignin and cellulose with water-only pretreatment. (c) Log R0 versus removal of xylan, lignin and cellulose with 0.05% (w/w) H2SO4. In (b) and (c): crossed squares = xylan removal (10 mL/minute), solid squares = xylan removal (25 mL/minute); open squares = xylan removal (62.5 mL/minute); crossed triangle = lignin removal (10 mL/minute), solid triangle = lignin removal (25 mL/minute), open triangle = lignin removal (62.5 mL/minute); crossed circle = cellulose removal (10 mL/minute); solid circle = cellulose removal (25 mL/minute); open circle = cellulose removal (62.5 mL/minute).
