“…(7)- (11). For example, Corujo et al [31] reported that CO concentration was increased and CO2 concentration was decreased with the increase of Ni loading from 0.4 to wt.% [7], which is consistent with the promotion of the water-gas shift reaction (Eq. (6)).…”

“…The gas composition performance of biomass catalytic steam gasification has also been studied by other researchers [1,31,40,66]. Among the aforementioned reports for investigating the influence of Ni loading on gas concentrations during steam reforming of hydrocarbons, it was found that H2 was increased and concentrations of CH4 and C2-C4 were reduced.…”

“…It is demonstrated from Figure 5 that the total amount of coke deposition was 0.1 wt.% of the used NiO-ZnO-Al2O3 catalyst with a Ni molar ratio of 35%, which can be considered as negligible indicating that coke resistant catalysts have been obtained after adding Zn during the synthesis in this work. Corujo et al [31] reported more than 5…”

“…The influence of Ni content on hydrogen production has been reported by other researchers. For example, Corujo et al [31] investigated the catalytic activity of a Ni/Dolomite catalyst for the gasification of forestry residue in the presence of steam. They reported that the optimal result in terms of hydrogen production was found with the catalyst containing the smallest amount of NiO (0.4Ni/Dolomite).…”

“…For enhanced catalytic performance and thermal stability, various supports (such as, zeolites [4,5,7,28,29], dolomite [1,22,30,31], olivine [21,32], other metal and metal oxides such as La, Fe, CeO2, SiO2, ZrO2, TiO2, MgO, ZnO, Al2O3 [10,[33][34][35][36][37][38][39]) have been applied to change the interactions between support and metal particles which may thereby influence the catalytic properties. Particularly, alumina has been widely investigated as a catalyst support due to high activity and low cost in the reforming process [33][34][35]40].…”

Hydrogen production from the thermochemical conversion of biomass was carried out with nano-sized NiZnAlOx catalysts using a two-stage fixed bed reactor system. The gases derived from the pyrolysis of wood sawdust in the first stage were catalytically steam reformed in the second stage. The NiZnAlOx catalysts were synthesized by a co-precipitation method with different Ni molar fractions (5, 10, 15, 25 and 35%) and a constant Zn:Al molar ratio of 1:4. The catalysts were characterized by a wide range of techniques, including N2 adsorption, SEM, XRD, TEM and temperature-programmed oxidation (TPO) and reduction (TPR). Fine metal particles of size around 10-11 nm were obtained and the catalysts had high stability characteristics, which improved the dispersion of active centers during the reaction and promoted the performance of the catalysts. The yield of gas was increased from 49.3 to 74.8 wt.%, and the volumetric concentration of hydrogen was increased from 34.7 to 48.1 vol.%, when the amount of Ni loading was increased from 5 to 35%. Meanwhile, the CH4 fraction decreased from 10.2 to 0.2 vol.% and the C2-C4 fraction was reduced from 2.4 vol.% to 0.0 vol.%. During the reaction, the crystal size of all catalysts was successfully maintained at around 10-11 nm with lowered catalyst coke formation, (particularly for the 35NiZn4Al catalyst where negligible coke was found) and additionally no obvious catalyst sintering was detected. The efficient production of hydrogen from the thermochemical conversion of renewable biomass indicates that it is a promising sustainable route to generate hydrogen from biomass using the NiZnAl metal oxide catalyst prepared in this work via a two-stage reaction system.

High (≥95 % C) yields of n-hexane and n-pentane were obtained by hydrogenolysis of aqueous sorbitol and xylitol, respectively, at 413-443 K by using the Ir-ReOx /SiO2 catalyst combined with H-ZSM-5 as a cocatalyst and n-dodecane as a cosolvent. The direct production of n-hexane from glucose or cellobiose can be achieved by using the same system. The catalyst can be reused simply by the removal of the n-dodecane phase, which contains the product alkane, and the addition of fresh n-dodecane and substrate.
