Investigation of the Behaviour of Mn Doped Ceo2 Catalyst For Ethanol Steam Reforming Reaction

The effect of mn on performance of ceo2 in ethanol steam reforming was studied# mn doped ceo2 was prepared by co-precipitation method and analyzed by bet, xrd and tpr# cemno2 showed the acceptable conversion (31%) and hydrogen yield (57%)# the result of the analysis revealed higher specific surface area of the introduced catalyst than ceo2 and mnox# it was also indicated that although ce without mn had the higher conversion but it happened because of more ch4 selectivity (34% @ 500 °c)# mn conducted the reaction to more co2 generation and also it was an effective metal for wgs and esr reactions by adsorbing steam and ability of oxygen mobility#
