Abstract:
This study aims to evaluate the potential of hydrothermal liquefaction (HTL) as a sustainable pathway for the valorization of two-phase olive mill waste (TPOMW) into biocrude. Using real production data from Andalusia and a representative feedstock composition, the research applies different predictive models to estimate bio-oil yields under fixed HTL conditions (300.°C, 30.min, specific water/mass ratio). The approach combines theoretical yield predictions and a kinetic model proposed in literature, with the goal of providing a realistic assessment of large-scale implementation potential. Taking into account the total amount of waste available, the moisture content and the average value for obtained bio-oil yield, a value of 233.4 ktons of bio-oil could be produced by the HTL of TPOMW in Andalucía. These predictions will be contrasted with the results of laboratory-scale HTL tests to validate the accuracy and applicability of the model.
