“…The addition of Mg to the catalytic formulation leads to the formation of mixed splinel phases and basic sites that have been proven to improve the CO 2 conversion and the overall stability [75,76,83]. Depending on the synthetic routes, the interaction, and the dispersion of Ni 0 over the support could be increased allowing the increases in both activity and resistance to coke formation [77,[84][85][86][87][88]. Silica has also been investigated as a possible support for Ni in dry and combined reforming.…”

“…Although using silica as a support facilitates the reduction in Ni species, weak interaction between active phase and support causes rapid deactivation (from 90% to 80% for both CH 4 and CO 2 after 100 h of reaction at 750 • C) [89]. High surface area values and the possibility to obtain support with a specific lattice structure have been claimed as the responsible for the performances of Ni/SBA-15, Ni/MCM41 or other amorphous silica supports [60,88,[90][91][92][93][94]. Good results in dry, combined and tri-reforming of methane have also been obtained with Ni/ZrO 2 catalysts well-known to be stable at high temperatures [88,[95][96][97][98].…”

Catalytic Upgrading of Clean Biogas to Synthesis Gas

et al. 2022

Clean biogas, produced by anaerobic digestion of biomasses or organic wastes, is one of the most promising substitutes for natural gas. After its purification, it can be valorized through different reforming processes that convert CH4 and CO2 into synthesis gas (a mixture of CO and H2). However, these processes have many issues related to the harsh conditions of reaction used, the high carbon formation rate and the remarkable endothermicity of the reforming reactions. In this context, the use of the appropriate catalyst is of paramount importance to avoid deactivation, to deal with heat issues and mild reaction conditions and to attain an exploitable syngas composition. The development of a catalyst with high activity and stability can be achieved using different active phases, catalytic supports, promoters, preparation methods and catalyst configurations. In this paper, a review of the recent findings in biogas reforming is presented. The different elements that compose the catalytic system are systematically reviewed with particular attention on the new findings that allow to obtain catalysts with high activity, stability, and resistance towards carbon formation.

“…The tri-reforming of methane (TRM) arises as an emerging practical approach for the methane reforming process. − The TRM reaction is a combination of SRM, POM, and DRM in a reliable compact process. Taking advantage of TRM, the syngas generation becomes eco-friendly due to the reduction of CO 2 greenhouse emissions to reform methane with relatively low energy consumption.…”

“…Recent efforts have thus been made to design new catalysts to TRM, where unsupported and supported solids, including non-noble metals and monometallic and bimetallic noble metal catalysts have been tested. − Although these catalysts contain plenty of advantages for the TRM reaction, several limitations such as limited structural stability under H 2 -rich conditions, coking, and sintering represent challenges for a tri-reforming catalyst.…”

Investigation of the Deactivation Behavior of MeMo/La₂O₃-Al₂O₃- and MeMo/Nb₂O₅ Supported Catalysts (Me = Pt, Ni, and Co) in Tri-Reforming of Methane

et al. 2023

The deactivation behaviors of MeMo/La2O3-Al2O3- and MeMo/Nb2O5 supported catalysts were investigated in the tri-reforming of methane (TRM). Characterizations by XRD, SEM-EDS, HRTEM, XPS, FTIR, and Raman spectroscopies were performed, after testing the catalysts in distinct TRM reaction conditions. The effects the transition metal components had on the causes of the deactivations of the solids were evaluated. The reaction conditions favored PtO x species residing in close contact with Mo sites to form a PtMo alloy. This enhanced the CH4 activation avoiding carbon accumulation in PtMo/Nb2O5. In contrast, LaPtO x [Pto]n surface oxygen species formation neither avoided sintering of the Pto particles on Mo/La2O3-Al2O3 nor oxidized the deposited carbon. The incorporation of Co in Mo/La2O-Al2O3 and Mo/Nb2O5 caused the continuous reoxidation of Co species because of the presence of O2, CO2, and steam reactants during the TRM reaction. Significant coke depositions on the Nio sites of NiMo/La2O3-Al2O3 and NiMo/Nb2O5 by the contribution of Boudouard and methane cracking reactions were observed, in short-term stability runs.

For the first time, a catalyst containing 5wt.% Ni supported on a hydroxyapatite support (HAP) has been synthesized and evaluated in tri‐reforming of methane (TRM) for synthetic gas (syngas) production. Nickel nanoparticles could be easily formed on HAP surface by using the conventional incipient wetness impregnation technique. In TRM, under unfavorable reaction conditions from the thermodynamic point of view (e.g. medium reforming temperature of 700‐800 °C, low steam‐to‐carbon ratio, etc.), this catalyst showed high methane conversion (up to 90%), however, some deactivation took place. The latter could be explained by both the thermal sintering of nickel nanoparticles and the solid carbon formation. The impact of the main operational parameters has been studied. Increasing the reaction temperature, the molar ratio of oxygen‐to‐carbon and steam‐to‐carbon ratio are favorable for the methane conversion and mostly for the stability of the catalyst. High methane conversion of ca. 90% with a perfect catalytic stability during 300 hours‐on‐stream could be achieved at 800 °C and 1.4 bar, using a mixture containing low ratio of oxidant‐to‐carbon (molar ratio of CH4/CO2/H2O/O2/N2 = 1.0/0.67/0.9/0.1/0). These results offer the opportunity to further design an optimal Ni/HAP catalyst by improving metal‐support interaction and downsizing nickel nanoparticles.
