“…From the DTG profiles, it could be found that there was a significant weight loss around 298 C for Ni/Ce-SBA-15 (R ¼ 0.04) sample, while there was a significant weight loss around 700 C for Ni/SBA-15 and Ni/ Ce-SBA-15 (R ¼ 0.06) samples. These results revealed that most of the carbon species over Ni/Ce-SBA-15 (R ¼ 0.04) sample were relatively active carbon species, which was beneficial to prevent the deactivation of sample to some extent [56], whereas more graphitic carbon species have been formed over the Ni/SBA-15 and Ni/Ce-SBA-15 (R ¼ 0.06) samples. The deposition of a large amount of graphitic carbon i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 3 7 ( 2 0 1 2 ) 1 9 e3 0 on the surface of catalysts decreased the catalytic activity during the CO 2 reforming of methane.…”

“…The weight loss peak at low temperatures (250e350 C) can be attributed to the oxidation of active carbon, or amorphous carbon, and the one at high temperatures (>550 C) can be attributed to the oxidation of the inert carbon, namely, graphitic carbon [56,57]. The total weigh loss of spent samples increased with the following sequence: Ni/Ce-SBA-15 (R ¼ 0.04) (7.6%) < Ni/Ce-SBA-15 (R ¼ 0.06) (9.6%) < Ni/SBA-15 (11.2%).…”

“…It has been reported that introducing Zr, Ce, and Mg into a silica support markedly promoted Ni dispersion [28][29][30][31]. Based on these previous contributions, it is desirable to prepare a highly dispersed Ni catalyst using non-porous supports without diffusion limitation.…”

Abstract:The production of hydrogen-enriched syngas from the thermo-chemical conversion of biomass was studied using Ni/CaAlO x catalysts prepared by coprecipitation method. The effect of Ca addition with different molar ratios of Ca:Al (1:3, 1:2, 1:1, 2:1, 3:1) on the properties and catalytic behaviour in relation to syngas production and the coke formation on the surface of the catalysts were investigated.Catalysts were characterized by BET, XRD, TPR, SEM, and TEM. The SEM and TEM results showed that rod-shaped nano-particles were highly dispersed on the surface of the catalyst. The particle size of NiO was slightly affected with the increase of Ca content in the catalyst. It appeared that the selectivity of CO was increased and the selectivity of CO 2 was reduced with the increase of Ca addition to the catalyst. For example, CO 2 concentration was reduced from 20 to 12 Vol.%, when the molar ratio of Ca/Al was increased from 1:3 to 3:1 for the Ni/CaAlO x catalyst; it is suggested that the water gas shift reaction was inhibited and CO 2 reforming reactions were promoted in the presence of the catalyst with higher Ca content. The CO/H 2 molar ratio could be manipulated by changing the Ca content in the catalyst, while the H 2 concentration remained almost constant (around 45 Vol.%). Thus, using the Ni/CaAlO x catalyst developed in this work could provide a promising route to control the syngas composition, which is an important factor for syngas applications.

“…However, Ni particles could still suffer from sintering or coke formation at high temperature, which drastically affects the catalytic performances. Consequently, researchers have intensified their efforts to solve these problems through several procedures such as incorporation of small amount of rare and alkaline earth metals over nickel based catalysts [5][6][7] or changing supports type and enhancing metal-support interaction [8,9].…”

Effect of pore geometry of mesoporous supports on catalytic performances in methane reforming

Abstract-Catalysts prepared using three dimensional SBA-16 silica support (composed of micropores and cage-like mesopores) were tested in the reaction of methane dry reforming, in comparison with 2D hexagonal mesoporous SBA-15 support. The samples were evaluated by N2 sorption and X-Ray diffraction (XRD) for the assessment of their textural and structural properties. The reducibility was characterized by temperature programmed reduction (TPR). The catalytic performances were evaluated in methane dry reforming and spent catalysts (after reaction) were characterized for the evaluation of sintering and coke formation by TPH/MS, XRD and HR-TEM.
