Highlights
- Optimum delignification temperature of DES (160 °C) is lower than PIL (180 °C)
- 93.8 % delignification is achieved using DES in the microwave reactor
- A first principle-based delignification kinetic model is proposed
- Kinetic parameters and activation energies are determined for all systems
- Microwave delignification is 12 times faster than the oil-bath heating
