- Abstract
New data on total organic carbon (TOC) reduction and H2 production were obtained by using supercritical water oxidation of lactose with and without oxidant agents (H2O2 and t-BHP) in a continuous Inconel 625 flow reactor. The oxidation reactions were carried out at 550 and 700 °C, 22.5 MPa, 0.025 g/g (2.5 wt%) lactose concentration, feed flow rate of 5 g · min−1, and a total reaction time of 90 min. The average production of H2 yielded 4.5 mol/mol lactose with TOC reduction of ∼99 %. The results obtained in this study with supercritical water oxidation (SCWO) may be used to generate energy via production of H2 from dairy industry effluents.
