Catalytic oxidation of toluene and tetralin in supercritical carbon dioxide

The catalytic total oxidation of toluene and tetrahydronaphthalene (tetralin) in supercritical carbon dioxide over a 0.5% platinum {gamma}-alumina catalyst was studied in a fixed-bed reactor. Toluene oxidation experiments were performed at 618, 633, 648 and 663 K, and at 7.93, 9.31 and 10.7 MPa. Tetralin oxidation experiments were performed at 573, 598, 623 and 648 K and at 8.96 and 10.0 MPa. Inlet concentrations of toluene and tetralin were varied in the ranges 569 to 2,858 ppm (mass/mass) and 1,420 to 3,648 ppm, respectively. Reactions were run at excess oxygen with a 25:1 molar ratio of oxygen to toluene and a 15:1 molar ratio of oxygen to tetralin. A stepwise mechanism was postulated for the oxidation reaction to describe the kinetics of toluene and tetralin oxidation in supercritical carbon dioxide, and the reaction orders and activation energies were determined.
