- W2358001818 abstract "Addition of rare earth oxide CeO 2 with variable valences to La 2O 3 formed a mixture of rare earth oxides. This mixture can be used as the catalyst for the reduction of SO 2 by CO. In a fixed bed flow reactor, experimental were investigated for studing the activation process of this catalyst and effect factors such as temperature and concentration ratio of reactant on the activation reaction under the following conditions: composition of the gas mixture SO 2∶CO=1∶3, balancing with N 2 and feed flow rate 1000 mL/min. The phase structure changes of this catalyst were expressed with XRD and XPS. The results demonstrated that the activation temperature of CeO 2 La 2O 3/γ Al 2O 3 is 50~100℃ lower than that of a single component La 2O 3/γ Al 2O 3 or CeO 2/γ Al 2O 3, and the mixture of rare earth oxides has higher activity on catalytic reduction of SO 2 by CO. It's most likely that the result reveals on the synergism between CeO 2 and La 2O3." @default.
