Fe salts as catalyst for the wet oxidation of o-chlorophenol
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 ℃. 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 nearly100% of o-chlorophenol were removed at 150 ℃ 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 k J/mol in the temperature range of100-175 ℃. 作 者： XU Xin-hua HE Ping JIN Jian HAO Zhi-wei 作者单位： Department of Environmental Engineering, Zhejiang University, Hangzhou 310027, China 期 刊： 浙江大学学报B（英文版） SCI Journal： JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE B 年，卷(期)： 2005, 6(6) 分类号： X703 X131 Keywords： Fe o-chlorophenol Catalytic wet air oxidation Kinetic【Fe salts as catalyst for the wet oxi】相关文章：
