BIOMASS
› Abundantly available
› Less regional dependence
› Convert waste to energy
› Low
Conversion
to liquid and
energy density

HYDROTHERMAL LIQUEFACTION
› Converts wet biomass to
bio-oil.
› Operation conditions
› Temperature: 250-400 °C
› Pressure: 100-300 bar
› Hydrolysis of lignocellulosic
biomass
