Kinetics of ethanol oxidation in subcritical water
Ethanol oxidation in subcritical water was examined at 25 MPa in the temperature range of 260–350 °C with equivalence ratio of 0.6. With oxygen as the oxidiser, the overall first-order decomposition reaction parameters were determined to be 10 2.9 ± 0.4 s −1 for the pre-exponential factor and 53.8 ±...
