Hydrothermal liquefaction (HTL) is a technology aimed towards conversion of biomass into liquid components by processing under hot, pressurized aqueous conditions. Processum’s pilot system aimed for liquefaction has a temperature and pressure capacity of up to 450 °C and 350 bar, respectively. The pilot simulates a continuous process and is equipped with a feeding chamber and a recovery vessel. This pilot can also be used for small scale HTC conversion.
