A review on catalyst development for conventional thermal dry reforming of methane at low temperature

Abstract

Carbon dioxide (CO 2 ) utilization and conversion, as one of the main parts of carbon capture, utilization, and storage (CCUS), is not only considered an important way to mitigate global warming but also an attractive industrial route to produce valuable fuels and chemical feedstocks. Catalytic dry reforming of methane (DRM) is a promising technology for carbon dioxide utilization and conversion as it can produce syngas, carbon monoxide (CO), and hydrogen (H 2 ) for widespread industrial production processes. In most studies of the DRM reaction, a relatively high operational temperature (i.e., >700 C) has been applied since the reactivity limitation of widely used Ni-based catalysts at low temperatures and the extremely endothermic property of the DRM reaction. However, high cost and high requirement of thermal stability for catalysts have become a severe problem impeding the further commercialization of DRM technology. Decreasing the operational temperature (i.e., <700 C) is considered a promising way for further application of the DRM route to convert CO 2 and produce syngas. However, traditional Ni-based catalysts suffered from unsatisfied reactivity and severe coke formation, leading to quick deactivation at low temperatures. Developing a catalyst with excellent catalytic activity, coke resistance, and improved thermal stability is necessary for low-temperature DRM reactions. In recent years, with significant development in materials, catalyst design, and computational simulation, some synthesized catalysts have achieved considerable improvement in catalytic performance in low-temperature DRM. Hence, a review of recent development on low-temperature DRM catalysts is provided here to further guide and profoundly understand catalyst design for low-temperature DRM.

Integrated CO2 capture and utilization: a review of the synergistic effects of dual function materials

“…79,80 The supports used in most research are Al 2 O 3 , SiO 2 , ZrO 2 , CeO 2 , zeolites, and metal–organic framework (MOF) derived materials. 81 Some novel support materials have been developed in recent years, such as single crystalline metal oxides and crystalline oxides. Song et al 82 designed a Mo-doped Ni DRM catalyst on a single-crystalline MgO support, which showed excellent resistance to sintering and coking with over a reaction time of >850 h. Subsequently, Xiao and Xie 83 established a low-temperature DRM catalyst that operated effectively at 450 °C by anchoring single-crystalline Ni particles on porous single-crystalline CeO 2 monoliths, which led to suitable MSI that improved both catalytic activity and durability.…”

Application of ZrO2-Based Hierarchical Nanofibers as a Promoter in Ni Catalyzed Methane Dry Re-Forming

“…It is well-known that the high oxygen transport of ZrO 2 provides protection against coke formation . However, it has also been shown that the relatively weak metal–support interactions (MSIs) of Ni with ZrO 2 lead to deactivation by sintering. , To mitigate this effect, Tathod et al deposited a thin layer of MgAlO x MO nanosheets, derived from layer double hydroxide (LDH) NPs, as an intermediate strongly interacting oxide support. This unique hierarchical configuration was shown to provide superior performance and stability in DRM.…”

Boosting hydrogen production at room temperature by synergizing theory and experimentation

“…[2][3][4][5][6] Methane conversion produces hydrogen in addition to carbon monoxide, hydrocarbons, or alcohols, which are essential building blocks of the chemical industry. There are different routes to convert methane to hydrogen, including steam reforming of methane (SRM), 7,8 dry reforming of methane (DRM), 9,10 partial oxidation of methane (POM), 11 non-oxidative coupling of methane (NOCM), 12 and catalytic decomposition of methane (CDM). 13 Table 1 summarizes the catalysts and reaction temperatures used in these methods.…”
