Abstract (EN): Carbon nanotubes (CNTs) were used as catalysts in the removal of 2-nitrophenol (2-NP) by catalytic wet peroxide oxidation (CWPO). Different CNTs were synthesized by catalytic chemical vapour deposition (CVD) using Fe/¿-Al2O3, as described elsewhere (Purceno et al., 2015 and Martin-Martinez et al., 2016). A fluidized-bed reactor was employed by feeding a gas mixture of hydrogen and: i) ethylene alone for 30 min (sample E30); ii) acetonitrile for 20 min, followed by ethylene for 20 min (sample A20E20); iii) acetonitrile for 20 min, followed by ethylene for 10 min (sample A20E10); iv) ethylene for 10 min, followed by acetonitrile for 20 min (sample E10A20); and v) acetonitrile alone for 30 min (sample A30). The CNTs were tested for the oxidation of 2-nitrophenol (2-NP) in aqueous-phase (Martin-Martinez et al., 2016) and in biphasic conditions (cyclohexane-water) simulating oily wastewater effluents as described in previous works (Diaz de Tuesta et al., 2018). Both systems were modelled by using kinetic power-law equations, following a methodology presented previously (Diaz de Tuesta et al., 2017).
