제목 Hydrogen Production by Steam Reforming of Glycerol over Spherical Ni-based modified Catalyst
초록 During the synthesis of biodiesel from biomass, about 10% of glycerol was formed as a main byproduct. Increasing biodiesel production has resulted in over-production of glycerol. Steam reforming (SR) of glycerol is one of the common processes to produce hydrogen or synthesis gas. And Ni-based catalysts are widely used in SR of glycerol.
In this study, the structured M-Ni/γ-Al2O3, (M : K, Ca, Sr) catalyst were prepared by dry impregnation method. All catalysts have been employed for SR under at atmospheric pressure, 800 °C with gas hourly space velocity (GHSV) of 10,000 h-1 and feed molar ratios of Steam/Carbon=3. The prepared catalysts before and after the reaction were characterized by N2 physisorption, XRD, TPR, TGA, SEM-EDX, and TEM techniques.
It was found that the addition of alkali promoter on Ni/γ-Al2O3 inhibited methane formation in the SR of glycerol under the tested conditions. Moreover, the presence of alkali metal on Ni/γ-Al2O3 also promoted the stability of the catalyst through suppression of coke formation.
