title: [Catalytic degradation of naphthalene by CuO (-CeO2)/Al2O3].
abstract: Three catalysts CuO/Al2O3, CeO2/Al2O3 and CuO-CeO2/Al2O3 were prepared by the impregnation method. The textural and structural properties of the synthesized catalysts were characterized by N2 adsorption/desorption, SEM and XRD, and the effect of active ingredients, flow rate and reaction temperature on catalytic degradation of naphthalene (NaP) were investigated in fixed-bed reactor. The experimental results show that the prepared 18% CeO2/Al2O3 has a low catalytic activity of NaP. Nevertheless, both 18% CuO/Al2O3 and 9% CuO-9% CeO2/Al2O3 exhibit high catalytic activity whose removal efficiencies at 300°C can reach 91% and 89%, respectively. Besides, compared with CuO/Al2O3, CuO-CeO2/Al2O3 possesses a higher low-temperature activity. Furthermore, the variation of flow rates has little effect on the performance of two catalysts.
