- •
Paulownia, a promising lignocellulose material was selected for bioethanol.
- •
Holocellulose content as high as 61% was detected from raw paulownia.
- •
Dilute acid treatment increased xylose yield, while alkali enhanced lignin removal.
- •
Total reducing sugar yield of 92.8% was achieved in ultrasonic-assisted paulownia.
- •
Chemicals mainly destroyed amorphous region and surface of crystalline region.
