“…It should be noted that this high glycerol total conversion has been observed by all researchers that have investigated this reaction (Cheng et al 2011;Ebshish et al 2012). GC analysis revealed that the gaseous products were H2, CO2, CO, and CH4, which agreed with previous work showing that these are the major gaseous products of glycerol steam reforming at 400 °C (Hirai et al 2005;Zhang et al 2007;Dou et al 2014;Siew et al 2014;Gallegos-Suárez et al 2015). Hydrogen yield and selectivity (%) are presented in Fig.…”

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.

“…A statistical approach to study the reforming of glycerol to produce hydrogen using a fixed bed reactor of nickel-based catalyst was carried out by Douette et al (2007), who examined the effects of the reformer temperature, oxygen to carbon ratio, and steam to carbon ratio. Hirai et al (2005) reported that glycerol steam reforming over a Ru/Y 2 O 3 catalyst exhibited a H 2 selectivity of about 90% and complete conversion of glycerol at 600C. Zhang et al (2007) produced H 2 through the glycerol steam reforming over ceria-supported metal catalysts and found that a glycerol conversion of 100% could be achieved at 400C.…”

“…Adhikari et al (2007b) studied steam reforming of glycerol using an alumina-supported metal catalyst over a range of conditions and showed that, at high temperatures, high gas yield was reached and selectivity of up to 70% was obtained. Steam reforming of glycerol was evaluated on Ni/CeO 2 , Ni/MgO, and Ni/TiO 2 catalysts (Hirai, et al, 2005). The results show that Ni/CeO 2 is the best catalyst, which gives a H 2 selectivity of 74.7% and a glycerol conversion of 99% at 600C.…”

“…To date, although there have been a few studies on the use of catalysts active for methane and/or ethanol steam reforming such as Ni-based catalysts for steam reforming of glycerol (Adhikari, et al, 2007a;2007b and2008;Czernik, et al, 2002;Douette, et al, 2007;Hirai, et al, 2005;Zhang, et al, 2007), little has been found in the literature on glycerol steam reforming with in-situ CO 2 removal. This forms the main motivation for carrying this study on the use of a commercial Ni-based catalyst and a calcined dolomite sorbent to investigate the feasibility of sorption enhanced steam reforming of glycerol for hydrogen production.…”

Catalytic steam reforming of glycerol for H 2 production has been evaluated experimentally in a continuous flow fixed-bed reactor. The experiments were carried out under atmospheric pressure within a temperature range of 400-700C. A commercial Ni-based catalyst and a dolomite sorbent were used for the steam reforming reactions and in-situ CO 2 removal. The product gases were measured by online gas analyzers. The results show that H 2 productivity is greatly increased with increasing temperature and the formation of methane by-product becomes negligible above 500C. The results suggest an optimal temperature of ~500C for the glycerol steam reforming with in-situ CO 2 removal using calcined dolomite as the sorbent, at which the CO 2 breakthrough time is longest and the H 2 purity is highest.

주제어 : 코발트알루미네이트, 금속-세라믹 복합체, 불균일계촉매, 글리세롤 개질반응 Abstract : In this study, we investigated the structure and properties of a highly heat conductive metal-ceramic core-shell CoAl2O4@Al micro-composite for heterogeneous catalysts support. The CoAl2O4@Al was prepared by hydrothermal surface oxidation of Al metal powder, which resulted in the structure with a high heat conductive Al metal core encapsulated by a high surface area CoAl2O4 shell. For comparison, CoAl2O4 was also prepared by co-precipitation method and also utilized for a catalyst support. Rh catalysts supported on CoAl2O4@Al and CoAl2O4 were prepared by incipient wetness impregnation and characterized by N2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), CO chemisorption, and temperature-programmed reduction (TPR). The properties of catalysts were investigated for glycerol steam reforming reaction for hydrogen production at 550 ℃. Rh/CoAl2O4@Al exhibited about 2.8 times higher glycerol conversion turnover frequency (TOF) than Rh/CoAl2O4 due to facilitated heat transport through the core-shell structure. The CoAl2O4@Al and CoAl2O4 also showed some catalytic activities due to a partial reduction of Co on the support, and a higher catalytic activity was also found on the CoAl2O4@Al core-shell than CoAl2O4. These catalysts, however, displayed deactivation on the reaction stream due to carbon deposition on the catalysts surface.
