| 6 | Characterization of La-promoted Ni/Al_2O_3 catalysts for hydrogen production from glycerol dry reforming显示文摘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%. | Kah Weng Siew Hua Chyn Lee Jolius Gimbun Chin Kui Cheng | 2014 | Journal of Energy Chemistry2014，23，1： | 1 |

| 11 | Catalytic performance of cement clinker supported nickel catalyst in glycerol dry reforming显示文摘The paper reports the development of cement clinker-supported nickel(with metal loadings of 5 wt%, 10 wt%, 15 wt% and 20 wt%) catalysts for glycerol dry(CO2) reforming reaction. XRF results showed that CaO constituted 62.0% of cement clinker. The physicochemical characterization of the catalysts revealed 32-folds increment of BET surface area(SBET) with the addition of nickel metal into the cement clinker, which was also corroborated by FESEM images. Significantly, XRD results suggested different types of Ni oxides formation with Ni loading, whilst Ca3SiO5 and Ca2Al0.67Mn0.33FeO5 were the main crystallite species for pure cement clinker. Temperature-programmed reduction analysis yielded three domains of H2 reduction peaks, viz. centered at approximately 750 K referred to as type-I peaks, another peaks at 820 K denoted as type-II peaks and the highest reduction peaks, type-III recorded at above 1000 K. 20 wt% Ni was found to be the best loading with the highest XGand H2 yield, whilst the lowest methanation activity. Syngas with lower H2/CO ratios(0.6 to 1.5) were readily produced from glycerol dry reforming at CO2-to-Glycerol feed ratio(CGR) of unity. Nonetheless, carbon deposit comprised of whisker type(Cv) and graphitic-like type(Cc) species were found to be in majority on 20 wt%Ni/CC catalysts. | Hua Chyn Lee Kah Weng Siew Maksudur R.Khan Sim Yee Chin Jolius Gimbun Chin Kui Cheng | 2014 | Journal of Energy Chemistry2014，23，5： | 1 |

| 16 | CO_2 reforming of glycerol over La-Ni/Al_2O_3 catalyst:A longevity evaluative study显示文摘This paper reports on the longevity of glycerol-dry(CO2) reforming over the lanthanum(La) promoted Ni/Al2O3 catalysts.The XRD results showed that the Ni particle was well-dispersed in the presence of La promoter.In addition,via the NH3-TPD analysis,it was found that the La promoter has reduced the acidity of Ni catalyst which may have explained the mitigation of carbon laydown.It was determined that the 3.0 wt% La-promoted Ni/Al2O3 catalyst possessed the largest BET specific surface area of 97 m2 g-1.Consequently,it yielded the best catalytic longevity performance with conversion attained more than 90%,even after 72 h of reaction duration.Significantly,it can be confirmed that the presence of CO2 during the glycerol dry reforming was essential in reducing carbon deposition,most likely via gasification pathway.This has ensured a stability of catalytic activity for a long reaction period(72 h). | Kah Weng Siew Hua Chyn Lee Maksudur R.Khan Jolius Gimbun Chin Kui Cheng | 2015 | Journal of Energy Chemistry2015，24，3： | 0 |
| 17 | 平行喷雾干燥中多相流动的非稳RANS及脱涡模拟(英文)显示文摘A detached eddy simulation(DES) and a k-ε-based Reynolds-averaged Navier–Stokes(RANS) calculation on the co-current spray drying chamber is presented. The DES used here is based on the Spalart–Allmaras(SA) turbulence model, whereas the standard k-ε(SKE) was considered here for comparison purposes. Predictions of the mean axial velocity, temperature and humidity profile have been evaluated and compared with experimental measurements. The effects of the turbulence model on the predictions of the mean axial velocity, temperature and the humidity profile are most noticeable in the(highly anisotropic) spraying region. The findings suggest that DES provide a more accurate prediction(with error less than 5%) of the flow field in a spray drying chamber compared with RANS-based k-ε models. The DES simulation also confirmed the presence of anisotropic turbulent flow in the spray dryer from the analysis of the velocity component fluctuations and turbulent structure as illustrated by the Q-criterion. | Jolius Gimbun Noor Intan Shafinas Muhammad Woon Phui Law | 2015 | Chinese Journal of Chemical Engineering2015，23，9： | 0 |
