Embodiment 1
[0108] The device for preparing bio-crude oil by continuous hydrothermal liquefaction of biomass of the present invention is used to process microalgae materials. Among them, the moisture content of the biomass of the microalgae material is 80%, the reaction temperature of hydrothermal liquefaction is 285°C, the system pressure is 9.0MPa, and the reaction time is 20 minutes. After 10 hours of stable operation of the reactor, 52.0% of crude oil can be obtained. The state is stable, and the fluctuation range of temperature and pressure is not obvious.
Embodiment 2
[0110] The device for preparing bio-crude oil by biomass continuous hydrothermal liquefaction of the present invention is used to process animal feces materials. Among them, the water content of animal manure is 86%, the reaction temperature of hydrothermal liquefaction is 300°C, the system pressure is 10.8MPa, and the reaction time is 30 minutes. After 10 hours of stable operation of the reactor, 60.2% of crude oil can be obtained, and the operation state is stable. The fluctuation range of temperature and pressure is not obvious.
Embodiment 3
[0112] The device for preparing bio-crude oil by biomass continuous hydrothermal liquefaction of the present invention is used to process kitchen waste materials.
