Corn stover
|
160–200 °C, 13–17 MPa, 40–80 min, water:ethanol as co-solvent
|
Removal of lignin reached to 90.05% and increased the enzyme accessibility

Corn stover
|
120 °C, 1450 psi, 30 min, ethanol as co-solvent
|
Increased sugar yield of 2 mm and 4 mm particles at a higher pressure, but decreased sugar yield of 1 mm as pressure increased

Corn stover, corn cob, and sorghum stalk (75% moisture)
|
50–80 °C, 17.5–25 MPa, 12–60 h
|
Pre-treatment significantly reduced the temperature from 160–170 to 50–80 °C and increased the enzyme accessibility 3- or fourfold compared to unpretreated
