چکیده انگلیسی
A quantitative kinetic model for the supercritical water partial oxidation of the mixture of acetic acid, naphthalene and phenol at 560 °C, 25 MPa was established. The model consisted a group of pathways that included two kind of compounds, which could be classified as stable cyclic compound (Int.1) and unstable ring-opening products (Int.2). The model was validated with the experimental data at oxygen ratio (OR) of 0 and 0.2, respectively. Results showed that the model could accurately predict the influences of reactants time on gas yields and intermediates concentrations. Reaction rate analysis indicated that the general trends of reaction rate at OR = 0 and OR = 0.2 were similar. The decomposition and steam reforming reactions of Int.2 were the main pathways for gas production. The oxygen during the gasification played a positive role in promoting the ring-opening reactions, which induced higher Int.2 production and increasing of steam reforming and decomposition rates, and finally increased the H2 production.
