Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The continuous catalytic oxidation of aqueous phenol solutions has been investigated using a series of trimetallic catalysts, called Mn-Sn-Sb/γ-Al2O3 catalysts in a packed bed reactor. The influence of the co-impregnation and successive impregnation were studied for the preparation of the catalysts. Descriptive statistics for different catalysts indicated that the catalyst which was loaded by the manganese oxides first and then by the stannum oxides and stibium oxides had a better activity and stability. Using this catalyst, phenol conversion and TOC reduction could get 90.6% and 83.1% respectively at 150°C, IMPa of oxygen partial pressure and space time of 27min. The leaching of metal ions was computed to negative correlation with the effluent pH for 100h operating at 120°C using pure oxygen as oxidant.
