Catalytic wet air oxidation of p-coumaric acid on CeO2, platinum and gold supported on CeO2 catalysts

Catalytic wet-air oxidation processes: A review

“…Experimental data, description of mass-transfer processes and reaction courses, as well as reactor simulation activities, which are required for successful commercial exploitation, have so far been presented only for model pollutants such as formic acid, acetic acid, succinic acid, cyclohexanol, cyanide and phenol [20,46,51,81,93,[128][129][130][131][132][133]. Béziat et al [128], who conducted the catalytic oxidation of aqueous solutions of acetic and succinic acid in a trickle-bed reactor, demonstrated that titaniasupported ruthenium catalysts exhibited excellent chemical resistance in a wide range of operating conditions.…”

Wet air oxidation of acetic acid over platinum catalysts supported on cerium-based materials: Influence of metal and oxide crystallite size

“…The use of catalysts can reduce the severity of WAO conditions [5,6]. Catalytic wet air oxifocused on studies involving CWAO by cerium-based heterogeneous catalysts [10,14,[20][21][22][23]. Under conventional reaction conditions, oxygen is in deficient proportions (i.e., the limiting reactant) compared with the pollutants, and thus one of the essential steps in the reaction pathway corresponds to the oxygen mobility from the support to the active metal crystallites [9].…”

Catalytic properties of carbon materials for wet oxidation of aniline

“…Wet air oxidation (WAO) is a mature process developed in the third quarter of the XX century, but still the centre of very active and contemporary research, especially in what concerns catalyst development [1][2][3][4]. Catalytic wet air oxidation (CWAO) consists in the total oxidation of the organic species present in effluents to CO 2 , N 2 and H 2 O under relatively mild conditions of temperature and pressure (125-220 • C, 5-50 bar), using oxygen or air as the oxidising source, provided that a suitable catalyst is used.…”
