| Abstract: | The attapulgite supported transition metals (Ni, Cu, Co or Fe) catalysts were prepared by precipitation method at constant loading (10 wt%) and investigated in the glycerol steam reforming reaction for H2 production under 400–750 °C, water/glycerol (W/G) = 3, N2 flow ratio = 0.16 L/min and WHSV = 6.46 h?1. The as-prepared catalysts were characterized by N2 adsorption-desorption, XRD, H2-TPR and TEM-EDS. The results shown different active metals presented various crystalline sizes and reduction properties. The experimental results revealed Ni/ATP and Co/ATP catalysts had more active for glycerol steam reforming than Cu/ATP and Fe/ATP catalysts, due to the fact that active metal Ni and Co have superior capacity to promote the necessary C | |
