“…Although some studies have revealed that noble metal-based catalysts performed well for ethanol steam reforming, [12][13][14] nickel based catalysts are one of the most attractive catalysts that have been investigated because of their effective catalytic activity and relatively low cost. [15][16][17] The sol-gel catalyst preparation method has been shown to confer high surface area and pore volume as well as high Ni dispersion for nickel-based catalysts. [18][19][20] In addition, the physical and chemical properties of the produced catalyst have been significantly influenced by the preparation methods using, for example, different Ni contents, 21 solution acidity, 22 solution reagent (citric acid etc.…”

Ni/SiO2 catalysts prepared by a sol-gel method have been investigated for hydrogen production via steam reforming of ethanol using a continuous flow, fixed bed reactor system. Chemical equilibrium calculations were also performed to determine the effects of temperature and molar steam to carbon ratio on hydrogen production. The acidity of the preparation solution (modified by nitric acid and ammonia) and calcination atmosphere (air and N2) were investigated in the preparation of the catalysts. BET surface area and porosity, temperature-programmed oxidation (TPO), X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used to characterise the prepared catalysts. The BET surface area was reduced when the solution acidity was lowered during the sol-gel preparation process. A pH value less than 2.0 was necessary to achieve high metal dispersion in the catalyst. Smaller NiO particles were obtained when the catalyst was calcined in N2. Material balances on ethanol steam reforming at 600 C using the prepared Ni/SiO2 catalysts were determined, and higher hydrogen production with lower coke deposition on the reacted catalysts were also obtained from the catalysts calcined in N2 atmosphere.

“…A large number of catalysts, including oxide catalyst [5][6][7][8], Nibased catalysts [9][10][11][12], Co-based catalysts [13][14][15], and noble metal catalysts [16][17][18], have been investigated for the hydrogen production by both the SRE and OSRE. The oxide catalysts exhibit low prices, but they also present a poor catalytic activity and an easy deactivation by carbon deposition.…”

“…Several basic oxides such as La 2 O 3 , MgO, ZnO, and CeO 2 are commonly used as supports (Tab. 2) [31,34,35,43,46,49,52,98]. The catalytic performances over these oxide supports are also dependent on the reaction temperature, the steam/ethanol ratio, and the Ni content [1,49,70,90,91].…”

“…Among the non-noble metals, Ni is the metal catalyst most often used in ESR due to its high activity, efficiency, and inexpensiveness [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. Indeed, Ni-based catalysts supported on Al 2 O 3 can realize full ethanol conversion (100 %) and very good hydrogen selectivity (96 % at 800°C) [46].…”

Effect of Supports and Promoters on the Performance of Ni‐Based Catalysts in Ethanol Steam Reforming

et al. 2020

Ethanol steam reforming (ESR) is one of the potential processes to convert ethanol into valuable products. Hydrogen produced from ESR is considered as green energy for the future and can be an excellent alternative to fossil fuels with the aim of mitigating the greenhouse gas effect. The ESR process has been well studied, using transition metals as catalysts coupled with both acidic and basic oxides as supports. Among various reported transition metals, Ni is an inexpensive material with activity comparable to that of noble metals, showing promising ethanol conversion and hydrogen yields. Additionally, different promoters and supports were utilized to enhance the hydrogen yield and the catalyst stability. This review summarizes and discusses the influences of the supports and promoters of Ni‐based catalysts on the ESR process.
