| Abstract: | Supercritical water oxidation of acrylic acid production wastewater was investigated using H2O2 as the oxidant. Reaction rate expression was achieved, and the reaction order of feed wastewater (based on COD), oxidant and water was assumed to be first, zero and zero, respectively. The resulting pre-exponential factor A was 4.97 s-1; the activation energy Ea was 20.64 kJ/mol; the induction time was about 8 s. |
