Characterization of La-promoted Ni/Al_2O_3 catalysts for hydrogen production from glycerol dry reforming

引用

Journal of Energy Chemistry 2014年第1期23卷 15-21页

作者： Kah Weng siew Hua Chyn lee Jolius Gimbun Chin Kui Cheng Centre of Excellence for Advanced Research in Fluid Flow Universiti Malaysia PahangLebuhraya Tun Razak26300 GambangKuantan PahangMalaysia Faculty of Chemical & Natural Resources Engineering Universiti Malaysia PahangLebuhraya Tun Razak26300 GambangKuantan PahangMalaysia

In the current paper, dry(CO2)-reforming of glycerol, a new reforming route, was carried out over alumina(Al2O3)-supported, non-promoted and lanthanum-promoted nickel(Ni) catalysts. Both sets of catalysts were synthesized via a wet co-impregnation procedure. Physicochemical characterization of the catalysts showed that the promoted catalyst possessed smaller metal crystallite size, hence higher metal dispersion compared to the virgin Ni/Al2O3catalyst. This was also corroborated by the surface images captured by the FESEM analysis. From temperature-programmed calcination analysis, the derivative weight profiles revealed two peaks, which represent a water elimination peak at a temperature range of 373 to 473 K followed by nickel nitrate decomposition from 473 to 573 K. In addition, BET surface area measurements gave 85.0 m2 g-1for the non-promoted Ni catalyst, whilst the promoted catalysts showed an average of 1% to 6% improvement depending on the La loadings. Significantly, reaction studies at 873 K showed that glycerol dry reforming successfully produced H2. The 2%La-Ni/Al2O3catalyst, which possessed the largest BET surface area, gave an optimum H2generation(9.70%) at a glycerol conversion of 24.5%.
