摘要
The catalytic performances of lanthanum strontium manganite (La0.8Sr0.2)Mn0.98O3, in catalytic wet oxidation (CWO) of a phenol solution under milder conditions of temperature (398-498 K) and pressure (P-o2 = 4 bar), in a batch reactor, have been investigated. Aim of this study is the evaluation of the effect of temperature, catalyst loading, phenol concentration and stirrer speed on phenol conversion. Experimental data obtained from the different test conditions are best-fitted to evaluate the effective reaction order and apparent activation energy. (C) 2008 Elsevier B.V. All rights reserved.
