Abstract: 
catalytic wet air oxidation (CWAO) of o-chlorophenol in wastewater was studied in a stainless steel autoclave using four different fe catalysts in the temperature range of 100–200 °C. Experimental results showed that high rate of o-chlorophenol and CODCr (Chemical Oxygen Demand, mg/L) removal by CWAO was obtained at relatively low temperature and pressure. The catalysts fe2(SO4)3, feSO4, fe2O3 and feCl3 all exhibited high catalytic activity. More than 93.7% of the initial CODCr and nearly 100% of o-chlorophenol were removed at 150 °C after 150 min with feSO4 as catalyst. The CWAO of o-chlorophenol was found to be pseudo-first order reaction with respect to o-chlorophenol, with activation energy of 75.56 kJ/mol in the temperature range of 100–175 °C.
