Review on the catalytic tri-reforming of methane - Part I: Impact of operating conditions, catalyst deactivation and regeneration

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

“…Moreover, an increment of the water partial pressure may cause a decrease in CO 2 conversion, which results in a negative reaction order for CO 2 conversion with respect to the partial pressure of water. This agrees with the thermodynamic predictions confirming the competition of the H 2 O and CO 2 oxidants during methane reforming reactions. ,, …”

“…This agrees with the thermodynamic predictions confirming the competition of the H 2 O and CO 2 oxidants during methane reforming reactions. 18,21,22 Thereby, methane reacts promptly with steam and oxygen, most probably during steam reforming and partial oxidation of methane reactions. This is in accordance with previous reports illustrating that these reactions are favored by the presence of steam and oxygen.…”

“…0.20 nm. 21,31 Moreover, Ni particles have mean sizes within 12−25 nm. The expected lattice at around 0.27 nm, coming from the (314) plane of Nb 2 O 5 is not detected in the high magnification HRTEM images illustrating low resistance against thermal effects.…”

Review on the catalytic tri-reforming of methane - Part II: Catalyst development

“…The present contribution belongs to a series of two review papers on TRM. The first one, entitled "Review on the catalytic tri-reforming of methane -Part I: impact of operating conditions, catalyst deactivation and regeneration" [33], has discussed the aspects of thermodynamic, mechanism, operating condition impact, and catalyst deactivation and regeneration. The second one (this work) provides a comprehensive overview on the rational design of TRM catalysts, including the following main sections: (i) active catalytic phases; (ii) catalyst supports; (iii) and catalyst promoters.…”

In Situ Studies of Single-Nanoparticle-Level Nickel Thermal Oxidation: From Early Oxide Nucleation to Diffusion-Balanced Oxide Thickening

“…Thermal oxidation of metallic nanoparticles is a fundamental gas–solid reaction, with significant scientific and technological impact in a broad range of applications including catalysis, − energy storage, − nanomaterial fabrication, , and so forth. In particular, the oxidation of metal nanocatalysts, desired or unwanted, plays a significant role in catalyst activation, operation, deactivation, and regeneration. , Besides that nickel (Ni) nanoparticles are widely used in catalytic chemical industries, , the advantage of Ni nanoparticle oxidation producing only one stable oxide phase without extra transformations of various oxidation states makes this a fundamentally important model system.…”
