✦ Synopsis

Algal cells of Dunaliella tertiolecta with a moisture content of 78.4 wt% were converted directly into oil by thermochemical liquefaction at around 300°C and 10 MPa. The oil yield was about 37% on an organic basis.

The oil obtained at a reaction temperature of 340°C and holding time of 60min had a viscosity of 150-330 mPas and a calorific value of 36 kJ g-~, comparable to those of fuel oil.
