Table 1 Pretreatment conditions at three kinds of factors for PH

From: Production of isoprene, one of the high-density fuel precursors, from peanut hull using the high-efficient lignin-removal pretreatment method

Factors Scope of optimizing factor Immovable factors
Time 30, 60, 90, 120 min 10% (w/v) solid loading, ratio of H3PO4 to H2O2 (1:9), at 100 °C
Ratio of H3PO4 to H2O2 (v/v) 1:9, 2:8, 3:7, 4:6, 5:5 10% (w/v) solid loading, at 100 °C for 60 min
Temperature 50, 60, 70, 80, 90, 100, 110 °C 10% (w/v) solid loading, ratio of H3PO4 to H2O2 (2:8) for 60 min
