| Abstract: | xMoO3-6CeO-Co3O4 catalysts with different Mo contents were prepared by coprecipitation method and impregnation method.CO conversion and sulfur tolerance properties of the catalysts were investigated.The catalysts were characterized by BET,SEM,FT-IR and H2-TPR techniques.The results indicated that the addition of MoO3 could improve the activity of the catalyst at low temperature.5.61MoO3-6CeO-Co3O4 catalyst possessed the best activities at low temperature,and CO conversion reached 98% at 40 ℃,While its performance for sulfur tolerance could last 90 min. |
