Hydrothermal Conversion of Manure up to Near-Critical Conditions: A Thermodynamic Equilibrium Approach

O. Yakaboylu, J. Harinck, K.G. Smit Gerton & W. De Jong
This study aims to investigate the behaviour of elements on compound and phase basis during the hydrothermal conversion of mixed pig-cow manure up to near critical temperatures and critical pressures. The software program FactSage 5.4.1 with a user-defined database has been used for thermodynamic equilibrium calculations. The temperature interval and the moisture content of the manure have been chosen as 120 °C - 360 °C and 80%, respectively. The results show that three phases are...
