英文摘要	a series of monolithic catalysts of mixed metal oxides (zno-zncr2o4/ceo2-zro2) for methanol auto-thermal reforming (atr) has been studied. the ceo2-zro2 modified zn-cr-oxide catalysts showed high selectivities and stabilities. characterization by xrd and tpr showed that the ce/zr molar ratio was an important factor for the stabilities of the zn-cr catalysts due to the redox properties of the ceo2-zro2. the optimal molar ratio of ce to zr was 4/1. the addition of the ceo2-zro2 mixed oxides decreased the crystallite size of the zn-cr oxide. operation parameters such as the ratios of oxygen to methanol and water to methanol were studied. the zno-zncr2o4/ceo2-zro2 catalyst exhibited very good stability during 1000 h test.
