“…Depending on the support material and the process conditions (pH, acid additives), the reaction can be steered towards enhanced hydrogen or hydrocarbon formation. Different metal oxides 4,14,18,32,35,36 can be used as a support for Pt particles in the APR along with zeolites 21,23,37 and carbon. 12,32,38 Carbon supports for Pt catalysts in the APR process have recently attracted much scientific attention.…”

aThe aqueous phase reforming (APR) of xylitol was studied over five Pt/C catalysts. The correlation between physico-chemical properties of the catalysts and catalytic performance was established. The Pt/C catalysts have different textural properties as well as different mean Pt cluster sizes and surface acidity. The average Pt cluster size was investigated by means of CO chemisorption as well as by TEM.The reaction was found to be structure sensitive and TOF linearly increases with increasing average Pt cluster size in the studied domain. The catalysts which possess higher surface acidity favoured higher rates of hydrocarbon production. On the contrary the Pt/C materials with lower acidities generated hydrogen with high selectivity and TOF.

“…Many studies on the catalytic reforming of model oxygenates under APR conditions have been reported recently [9][10][11][12][13]; ethanol, ethylene glycol, glycerol are typical examples. Information on mechanistic sequences that take place during APR is limited, and in the case of ethylene glycol (EG), Dumesic et al [13] suggested that reforming is initiated via dehydrogenation and formation of an adsorbed oxygenate (acetylinic dialcohol type) intermediate.…”

The performance of nickel, cobalt, and copper supported on silica as catalysts was evaluated for the glycerol steam reforming (GSR) reaction. The samples were characterized by nitrogen-porosimetry according to Brunauer-Emmett-Teller (BET) method, X-ray diffraction (XRD), and inductively coupled plasma atomic emission spectroscopy (ICP-AES), while the deposited carbon on the catalytic surface was measured with a CHN-analyzer. Catalysts were studied in order to investigate the effect of the reaction temperature on (i) glycerol total conversion, (ii) glycerol conversion to gaseous products, (iii) hydrogen selectivity and yield, (iv) selectivity of gaseous products, and (v) selectivity of liquid products. The results showed that the Ni based on silica (Ni/Si) catalyst was more active and produced less liquid effluents than the catalysts that used an active metal such as Co or Cu. Moreover, the H2 yield from the Ni/Si catalyst was very close to the theoretical maximum predicted by thermodynamics, and the CO2 production was favoured in comparison to CO production, which is important for use in fuel cells.
