N2 - The glycerol steam reforming was investigated on alumina supported molybdena catalysts (with 2, 5 and 12 wt.%) prepared by the sol-gel method and gel combustion. The catalysts were characterized by XRD, BET, UV-VIS, DRIFT, SEM and TEM. The catalytic performances were studied at 400-500°C, steam to glycerol molar ratio between 9:1 and 20:1 and feed flow rate 0.04-0.08 ml/min. The conversion is directly proportional to molybdena loading, while the hydrogen selectivity has reached greater value on catalyst with 2% MoO3. The optimum ratio steam to glycerol for reforming is 15:1 and for decomposition in syngas 9:1 and the ratio 20:1 favors water gas shift reaction.
