Biodiesel production from lipids in wet microalgae with microwave irradiation and bio-crude production from algal residue through hydrothermal liquefaction

- Cogeneration of biodiesel and bio-crude was proposed to make full use of microalgae.
- Total energy recovery was increased to 67.73% by utilization of microalgae residue.
- Remaining nitrogen in liquid fuel decreased to 16.02% by the cogeneration process.
- Lipids and proteins were prevented from interacting to form low-grade liquid fuel.
