Title
Hydrogen production from glycerol steam reforming over molybdena–alumina catalysts
Abstract

•Molybdena nanomaterials, a new catalyst for glycerol steam reforming•Species distribution varies from spherical particles to sharp and thin pieces.•Molybdena surface density has an influence on hydrogen yield.•The optimum ratio steam to glycerol for steam reforming, water gas shift reaction and syngas was investigated.

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.
