“…The same authors tested more liquid HC and OXYF under DR and POX conditions. Thus, n ‐heptane as gasoline surrogate, n ‐dodecane as diesel surrogate, toluene as representative aromatic compound, ethanol as OXYF representative, and CH 4 as molecule lacking CC and CO bonds were tested under the same conditions as in their 2006 publication .…”

Although natural gas is the main feedstock for the production of hydrogen and syngas, liquid hydrocarbons and oxygenated compounds are of interest for reasons associated with their local availability and their easiness to be stored and transported. This review focuses on steam, dry, and partial oxidation of liquid feedstock. The vast research work published in these fields does not allow for a full coverage of the entire literature. Instead, the authors present from both scientific and technical stand points the knowledge which seems more promising toward eventual improvements of commercial units and utilization of new catalytic formulations. Since traditional steam reforming is relatively very well covered by other reviews, this review has mainly focused on the relatively recent works on glycerol, a biodiesel production by-product, and the widely available and distributed commercial diesel/biodiesel. New promising catalytic formulations are proposed and are actually under testing for eventual commercial use. Nevertheless these catalysts might be eventually efficient for gaseous (e.g., CH 4 ) hydrocarbons conversion to syngas. Dry and partial oxidation has also been reviewed both globally and in an incremental way. All liquid feedstock tested are reported. Finally, this review tries to bridge the gap between fundamental and factual research in this field. Both are important but the interpretation of the results remains a strong function of each paper's main focus. This review does not pretend that this gap is fully bridged but it has the ambition to help the researchers as well as the practitioners in this area to synthesize the existing knowledge.

“…Due to the excessive temperature gradients at high conversion rate, the exothermic nature of the reaction and fast deactivation due to carbon deposition on the catalyst's surface, the development of efficient catalysts for the CPOM has been challenging. NPs of noble metals [Pt (Ji et al, 2001), Rh (Ruckenstein and Wang, 1999; Puolakka and Krause, 2007), Ru (Ashcroft et al, 1990), Pd (Vernon et al, 1990)] and non-noble metals [mainly Ni and Co (Wang and Ruckenstein, 2001)] supported on various oxide substrates have been studied in the CPOM reaction. Nickel is one of the most widely used active phases for CPOM (Miao et al, 1997; Ostrowski et al, 1998; Takehira et al, 2004; Wang et al, 2004).…”

Partial Oxidation of Methane to Syngas Over Nickel-Based Catalysts: Influence of Support Type, Addition of Rhodium, and Preparation Method

There is great economic incentive in developing efficient catalysts to produce hydrogen or syngas by catalytic partial oxidation of methane (CPOM) since this is a much less energy-intensive reaction than the highly endothermic methane steam reforming reaction, which is the prominent reaction in industry. Herein, we report the catalytic behavior of nickel-based catalysts supported on different oxide substrates (Al2O3, CeO2, La2O3, MgO, and ZrO2) synthesized via wet impregnation and solid-state reaction. Furthermore, the impact of Rh doping was investigated. The catalysts have been characterized by X-ray diffraction, N2 adsorptiondesorption at −196°C, temperature-programmed reduction, X-ray photoelectron spectroscopy, O2-pulse chemisorption, transmission electron microscopy, and Raman spectroscopy. Supported Ni catalysts were found to be active for CPOM but can suffer from fast deactivation caused by the formation of carbon deposits as well as via the sintering of Ni nanoparticles (NPs). It has been found that the presence of Rh favors nickel reduction, which leads to an increase in the methane conversion and yield. For both synthesis methods, the catalysts supported on alumina and ceria show the best performance. This could be explained by the higher surface area of the Ni NPs on the alumina surface and presence of oxygen vacancies in the CeO2 lattice, which favor the proportion of oxygen adsorbed on defect sites. The catalysts supported on MgO suffer quick deactivation due to formation of a NiO/MgO solid solution, which is not reducible under the reaction conditions. The low level of carbon formation over the catalysts supported on La2O3 is ascribed to the very high dispersion of the nickel NPs and to the formation of lanthanum oxycarbonate, through which carbon deposits are gasified. The catalytic behavior for catalysts with ZrO2 as support depends on the synthesis method; however, in both cases, the catalysts undergo deactivation by carbon deposits.

“…Hence, ethanol can be considered as an economically viable alternative green power source, which results in low pollutant emissions and controlled combustion (Tsiakarasa and Demin, 2001). In addition, relatively lower temperatures are required for a thermodynamically favorable reaction, where DRE is thermodynamically favorable above 318°C, compared to DRM (above 642°C) (Puolakka and Krause, 2007).…”

This paper presents a review on the developments in catalyst technology for the reactions utilizing CO 2 for high-temperature applications. These include dehydrogenation of alkanes to olefins, the dehydrogenation of ethylbenzene to styrene, and finally CO 2 reforming of hydrocarbon feedstock (i.e., methane) and alcohols. Aspects on the various reaction pathways are also highlighted. The literature on the role of promoters and catalyst development is critically evaluated. Most of the reactions discussed in this review are exploited in industries and related to on-going processes, thus providing extensive data from literature. However, some reactions, such as CO 2 reforming of ethanol and glycerol, which have not reached industrial scale, are also reviewed owing to their great potential in terms of sustainability, which is essential as energy for the future. This review further illustrates the building-up of knowledge that shows the role of support and catalysts for each reaction and the underlying linkage between certain catalysts, which can be adapted for the multiple CO 2 -related reactions.
