Kinetics of oxidation of para-aminophenol in supercritical water

Using continuous supercritical water oxidation experimental device, with H2O2 as oxidant, an experiment of the oxidation of para-aminophenol in supercritical water was made at 480 - 550 ℃ and 38 MPa. The results show that: the removal rate of para-aminophenol improves with the rising of the temperature and the extension of the resident time. In the case of 50% H2O2 excess, the reaction orders of CODCr and oxygen are 1.41, 0.23 respectively; the activation energy is 60.04 kJ/mol, and the arrhenius pre-exponential factor is 1.12 × 105.
