| 英文摘要 | The catalytic behavior of the various doped-MTiO(3) (M = Ca,Sr) catalysts for the oxidative dehydrogenation of ethane (ODHE) was examined in the temperature range of 700 similar to 850 degrees C. All of the, catalysts have certainly shown a catalytic activity for ODHE. When Li+ substituted Ti4+ in CaTiO3, a much better improvement in the C2H4 selectivity was observed. Selectivity 71.7% for C2H4, and conversion 87.8% for C2H6 could be obtained dyer the catalyst, CaTi0.9Li0.1O3-delta at 850 degrees C. The substitution of Sr for Ca in Ca1-xSrxTi0.9Li0.1O3-delta could give a high selecitivity (greater than or equal to 90%) for C2H4 in a very widely temperature range (700 similar to 850 degrees C). The effect of Li+ doping was explained by the increment of oxygen vacancy and the formation of non-fully reduced oxygen species. The non-fully reduced oxygen species are suggested as the active sites responsible for ethylene selecivity, and the reaction between reactants and catalyst is inhibited by CO2. |
