Production of 100 kg biodiesel generates 10 kg of glycerol as waste which is hazardous to environment. Considering environmental impact it's necessary to convert it into useful product. The steam reforming of glycerol was carried out to produce the hydrogen using magnesium with different supports. Various catalyst were prepared by wet impregnation method and performance was evaluated in a packed bed reactor over a wide range of operating conditions, and reaction parameters were optimized in

The various effects ofreaction temperature, H 2 O/glycerol molar ratio, and the feed flow rate on the steam reforming of glycerol over were also examined. Various catalyst prepared by the wet-impregnation methodand characterized by Xray diffraction technique, scanning electronmicroscopy (SEM) analysisand BET surface area analysis
