BIO-OIL PRODUCTION IN SUPERHEATED WATER

AARHUSUNIVERSITET

OUTLINE

› Why biomass?

› From biomass to bio-oil

› Bio-oil characteristics

› Outlook

AARHUSUNIVERSITET

BIOMASS

› Abundantly available

› Less regional

dependence

› Convert waste to energy

› Conversion to liquid and

gaseous fuels

›Low energy density

›High water content

›Complex

composition

›Impurities

AARHUSUNIVERSITET

HYDROTHERMAL LIQUEFACTION› Converts wet biomass

to bio-oil.

› Operation conditions

› Temperature: 250-400 °C

› Pressure: 100-300 bar› Hydrolysis of

lignocellulosic biomass
