- Temperature range of 330–390 °C was chosen as high temperatures (above 400 ° C ) will increase the dominance of gasification reaction .
The pressure range of 25–35 MPa was selected as it is above the critical pressure of water (22.1 MPa) to ensure water is in the subcritical and supercritical state.
-Mechanical stirring of the reactor is provided with a cyclic horizontal swing span of 2 cm at a frequency of 60 cycles/min. The ratio of biomass to water was set at 1:10 in all the experiments in this study, based on several works reported in the literature, in which liquefaction experiments were optimized at this ratio.
