“…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.…”

“…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.
