“…1, contains two additional positive peaks: one at 650 K and the most prominent peak at 731 K. The broad and asymmetric reduction peak at 731 K is probably associated with the reduction of Ni 2? , which is involved in strong interaction with the carbon support, a feature also observed by other groups [17,18].…”

Active carbon supported nickel catalysts prepared with nickel(II) nitrate and nickel(II) chloride precursors after reduction at 673 or 1173 K were investigated in the aqueous phase hydrodechlorination of 1,1,2-trichloroethene (TCE). These nickel catalysts facilitate the purification of water via decomposing TCE, but their catalytic properties depend on the chemistry of the nickel precursor used for Ni/C synthesis and pretreatment conditions. The chemistry of precursor catalysts affects the particle size, which in turn is correlated with catalytic activity. We observed the highest activity for Ni/C with the largest nickel particles. The application of high temperature reduction of nickel precursors increases the activity and minimizes the differences between the catalytic properties of the samples prepared from different salts.

“…It has been reported that there are two routes for the formation of carbon deposits: one is CH 4 decomposition and the other is CO disproportionation. CO disproportionation is thermodynamically favored in the lowtemperature region of 773-873 K while CH 4 decomposition is favored in the high-temperature zone at~1173 K [20]. In the experimental temperature range, CH 4 decomposition should be the dominant reaction for deactivation.…”

A new concept of combined coal gasification and methane reforming in a single reactor was proposed as an alternative path for syngas production using coal and coalbed methane. Here, the results of this process are summarized. The experimental work was carried out in a fixed-bed reactor. Methane cracking, CO 2 /steam reforming of methane over coal char, and the effects of chars made from different types of parent coal on methane conversion were examined. The catalytic effect of coal char on methane cracking and reforming increased with decreasing coalification degree. A synergistic effect was observed in that, while the coal char catalyzed the methane reforming reactions, gasification of the coal char took place simultaneously, which counter-balanced the deposition of carbon especially for the methane-steam-char system.

“…Table 4 presents a summary of the recent advances in the catalyst development for SRM in the past five years. The silicalite shell was grown around Al2O3 followed by impregnation to introduce Ni into the core of the catalyst The effects of Ce as a promotor for Ni-based catalyst was investigated [81] 5 wt % Ni/SiO 2 The catalytic performance of different Ni-based catalysts that were prepared using incipient wetness impregnation (SiO 2 , Al 2 O 3 ) and co-precipitation technique (Mg-Al and Zn-Al) was evaluated for SRM at low temperature (less than 600 • C) by Nieva et al [88]. The catalysts prepared via the co-precipitation route (Ni/Mg-Al and Ni/Zn-Al) was found to have better activity and stability compared to Ni/SiO 2 and Ni/Al 2 O 3 samples due to the higher metal-support interactions of these catalysts.…”

Recent Advances in Supported Metal Catalysts for Syngas Production from Methane

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.
