Supercritical water oxidation (SCWO) in hydrothermal flame regime has advantages over the oxidation in flameless regime. The main advantage is that the feed can be injected into the reactor at low temperatures, avoiding plugging and corrosion problems in a preheating system. However, there is a lack of kinetic data capable of properly describing the flame regime oxidation. In this study, new global reaction rate parameters for the oxidation of isopropyl alcohol in hydrothermal regime were adjusted from temperature profiles of our group's previous experimental data. The kinetics obey first order rate with regard to the fuel and the oxidant, and follows the Arrhenius law. The parameters are k(0) = (9.308 +/- 3.989) x 10(7) (m(3) s(-1) kmol(-1)) and E-a = 89.441 +/- 2.457 (kJ mol(-1)), and the least square error of the fitting was 10.8%. This kinetic model was applied in a parametric analysis of flame formation, and it was used to analyze the behavior of a supercritical water oxidation vessel reactors. The kinetic model is able to describe the behavior of the vessel reactor when working in steady state hydrothermal flame regime at subcritical injection temperatures (246 degrees C). The model predicts both flameless and hydrothermal flame regimes. (C) 2013 Elsevier B.V. All rights reserved.
