Preparation of Ni based catalysts to produce hydrogen from glycerol by steam reforming process
Abstract Nickel and Nickel Palladium catalysts supported on Al 2 O 3 ZrO 2 Al 2 O 3 ZrO 2 La 2 O 3 and on Olivine were synthesized using a combination of sol gel and wet impregnation methods. The influence of the formulation on their textural properties was examined by XRF, XRD and XPS. The influence of supports, promoters and temperatures of reactions was studied on glycerol steam reforming to produce hydrogen. C 3 H 8 O 3 and H 2 O mixture was fed into a fixed bed reactor in a molar ratio of S/C 5.0 (Steam/Carbon) and tested under atmospheric pressure at 800,700, 600 degC for 4 h. The most suitable catalyst was determined as Ni Pd/Al 2 O 3 ZrO 2 specifically in the process carried out at 800 degC, since it reached the highest hydrogen yield around 74%
