“…It was concluded that the introduction of Co induces the formation of Co-Ni alloys, and hence leading to smaller Ni particle sizes, especially at low Co/Ni ratios confirming previous findings [59]. A recent study has studied the controlled deposition of Fe-Ni nanoparticles onto Mg(Al)O periclase support using colloid synthesis route [60]. According to energy dispersive X-ray analysis (EDX) and X-ray absorption near-edge structure (XANES), the formation of a core-shell structure was confirmed with the Ni in the core and Fe in the shell side.…”

Abstract:Over the past few years, great attention is paid to syngas production processes from different resources especially from abundant sources, such as methane. This review of the literature is intended for syngas production from methane through the dry reforming (DRM) and the steam reforming of methane (SRM). The catalyst development for DRM and SRM represents the key factor to realize a commercial application through the utilization of more efficient catalytic systems. Due to the enormous amount of published literature in this field, the current work is mainly dedicated to the most recent achievements in the metal-oxide catalyst development for DRM and SRM in the past five years. Ni-based supported catalysts are considered the most widely used catalysts for DRM and SRM, which are commercially available; hence, this review has focused on the recent advancements achieved in Ni catalysts with special focus on the various attempts to address the catalyst deactivation challenge in both DRM and SRM applications. Furthermore, other catalytic systems, including Co-based catalysts, noble metals (Pt, Rh, Ru, and Ir), and bimetallic systems have been included in this literature review to understand the observed improvements in the catalytic activities and coke suppression property of these catalysts.

“…Dry methane reforming (DRM), also called CO 2 reforming, is considered one of the promising processes for chemical CO 2 utilization [1][2][3][4][5][6]. DRM leads to synthesis gas, a mixture of hydrogen and carbon monoxide, that is currently used as feedstock in liquid fuel production processes, such as Fischer-Tropsch or methanol synthesis [7].…”

“…Ni-based catalysts seem to be good candidates for DRM due to their availability, low cost and good catalytic performance [8,9]. However, the main drawback for their application is susceptibility to carbon formation leading to fast deactivation [3,4,6,10]. The methods proposed to improve stability of Ni-based catalysts, include, among others, the addition of a second metal and/or a promoter, or the choice of an appropriate support.…”

Yttrium modified Ni-based double-layered hydroxides were tested as novel catalysts in dry methane reforming. The catalysts were characterized by XRF, BET analysis, XRD, TPR-H 2 , TPD-CO 2 , TGA/DSC-MS, H 2 chemisorption and TEM. Co-precipitation with yttrium (III) nitrate hexahydrate resulted in increased specific surface area, smaller Ni crystallite size, enhanced reducibility, and higher distribution of weak and medium basic sites as compared to Y-free material. The DRM catalytic tests, carried out in the temperature range of 850-600 ºC, led to a significant improvement of activity, with the 1.5 wt % Y-promoted catalyst being the most efficient in converting both CH 4 and CO 2. Moreover, the 10 h test at 700 ºC further confirmed enhanced stability for this HTNi-Y1.5 catalyst. Higher CO 2 conversion than CH 4 conversion and less CO compared to H 2 proves that side reactions are occurring simultaneously.

“…Ruthenium nanoparticles were also successfully used for tuning the hydrogen/carbon monoxide molar ratio [16]. The coupling of nickel particles into alloys or spinel structures with other non-noble elements, such as Co [17,18], Cr [18], Mn [18][19][20], Ce [19,21], Fe [22,23], Zr [24], and Al [20,24], and alkali metals, such as Mg [25,26], K [27,28], and Na [29], was also reported as an effective approach to extend catalyst activity and reduce carbon formation [18,30]. Another technique used to preserve the small size of nickel particles is an application of a support that strongly interacts with the active metal.…”

Catalytic Activity of Nickel and Ruthenium–Nickel Catalysts Supported on SiO2, ZrO2, Al2O3, and MgAl2O4 in a Dry Reforming Process

Dry reforming of methane (DRM) is an eco-friendly method of syngas production due to the utilization of two main greenhouse gases—methane and carbon dioxide. An industrial application of methane dry reforming requires the use of a catalyst with high activity, stability over a long time, and the ability to catalyze a reaction, leading to the needed a hydrogen/carbon monoxide ratio. Thus, the aim of the study was to investigate the effect of support and noble metal particles on catalytic activity, stability, and selectivity in the dry reforming process. Ni and Ni–Ru based catalysts were prepared via impregnation and precipitation methods on SiO2, ZrO2, Al2O3, and MgAl2O4 supports. The obtained catalysts were characterized using X-ray diffractometry (XRD), inductively coupled plasma optical emission spectrometry (ICP-OES), Brunauer–Emmett–Teller (BET) specific surface area, and elemental carbon-hydrogen-nitrogen-sulphur analysis (CHNS) techniques. The catalytic activity was investigated in the carbon dioxide reforming of a methane process at 800 °C. Catalysts supported on commercial Al2O3 and spinel MgAl2O4 exhibited the highest activity and stability under DRM conditions. The obtained results clearly indicate that differences in catalytic activity result from the dispersion, size of an active metal (AM), and interactions of the AM with the support. It was also found that the addition of ruthenium particles enhanced the methane conversion and shifted the H2/CO ratio to lower values.
