Ni계 촉매상에서 글리세롤의 수증기 개질반응(Steam Reforming)에 의한 수소제조 연구

Abstract

Steam reforming (SR) of glycerol, a main by-product of manufacturing process of bio-diesel, for the production of hydrogen was investigated over the Ni-based catalysts. The Ni-based catalysts were prepared by an impregnation method, and characterized by N2 physisorption, CO chemisorption, XRD and TEM techniques. It was found that the Ni/γ-Al2O3 catalyst showed higher conversion and catalytic stability for the carbon formation than the other catalysts in the steam reforming of glycerol under the tested conditions. The results suggest that the steam reforming of glycerol over modified Ni/γ-Al2O3 catalyst minimized carbon formation can be applied in hydrogen station for fuel-cell powered vehicles and fuel processor for stationary and portable fuel cells.
