Catalytic wet air oxidation of sodium sulfide solutions. Effect of the metal-support and acidity of the catalysts
This work evaluates the catalytic wet air oxidation of sulfide present in spent caustic wastes generated during petroleum refining. Operating conditions were 70 °C and atmospheric pressure, with and without catalyst. Two supports (silica and clinoptilolite) and two metal oxides (vanadium and copper) were employed to produce different catalysts. The sulfide oxidation without catalyst displays a short induction period and complete oxidation of sulfide at 210 min. The most active catalysts were Cu/silica (CS) and V/clinoptilolite (VC), which improved the sulfide oxidation, achieving complete oxidation in 20 and 26 min, respectively. © 2011 Springer Science Business Media, LLC.
