Synthetic natural gas (SNG) can be obtained via methanation of synthesis (syngas). Many thermodynamic reaction details involved in this process are not yet fully understood. In paper, a comprehensive analysis reactions occurring the carbon oxides (CO and CO2) is conducted using Gibbs free energy minimization method. The equilibrium constants eight were calculated at different temperatures. effects temperature, pressure, ratio H2/CO (and H2/CO2), addition other compounds (H2O, O2, CH4, C2H4)...
This review summarizes the recent progress in methanation catalysts for SNG production, which will provide insights future design.
CO methanation reaction over the Ni/Al2O3 catalysts for synthetic natural gas production was systematically investigated by tuning a number of parameters, including using different commercial Al2O3 supports and varying NiO MgO loading, calcination temperature, space velocity, H2/CO ratio, pressure, time, respectively. The catalytic performance greatly influenced above-mentioned parameters. Briefly, large surface area support, moderate interaction between Ni support Al2O3, proper content (20...
We report a new strategy to synthesize the hierarchical mesoporous zeolite through design of mesoscale cationic surfactant cetyltrimethylammonium bromide (CTAB) micelle with cosolvent tert-butyl alcohol (TBA) and 1,3,5-trimethylbenzene (TMB) additive, by which formation mesostructure arose from condensing fragments on micelles. The silica Y or sodalite fragment is synthesized for first time, exhibited both typical diffraction zeolite. XRD, N2 adsorption−desorption, 27Al MAS NMR, FTIR,...
A series of α-Al2O3-supported Ni catalysts with different particle sizes (5–10, 10–20, and 20–35 nm) were prepared applied in the CO methanation reaction for production synthetic natural gas (SNG). The catalytic tests showed that nanoparticles influenced performance methanation, catalyst a nanoparticle size 10–20 nm highest conversion, CH4 yield, turnover frequency, lowest carbon deposition, demonstrating possibility improving Ni/α-Al2O3 SNG by controlling their size.
CeO<sub>2</sub>-decorated Ni/γ-Al<sub>2</sub>O<sub>3</sub> exhibited high activity, coking- and sintering-resistance for CO methanation because CeO<sub>2</sub> selectively deposited on the surface of NiO.
We report the preparation and characterization of Ni nanoparticles supported on barium hexaaluminate (BHA) as CO methanation catalysts for production synthetic natural gas (SNG). BHA with a high thermal stability was synthesized by coprecipitation method using aluminum nitrate, ammonium carbonate precursors. The support (Ni/BHA) were prepared an impregnation method. X-ray diffraction, nitrogen adsorption, transmission electron microscopy, thermogravimetric analysis, H2 temperature-programmed...
Nickel catalysts supported on the perovskite oxide CaTiO3 (CTO) were prepared by an impregnation method for CO methanation to produce synthetic natural gas (SNG). X-Ray diffraction, nitrogen adsorption, scanning electron microscopy, transmission thermogravimetric analysis, H2-temperature programmed reduction and desorption, photoelectron spectroscopy employed characterization of samples. The results revealed that Ni/CTO showed a better performance than Ni/Al2O3 at various reaction...
A series of ordered mesoporous Ni–Fe–Al ternary oxide composites were prepared via a one-pot evaporation-induced self-assembly (EISA) method and applied in CO methanation reaction to produce synthetic natural gas. The results showed that the catalyst with proper amount Fe species (10N1FOMA) had better both conversion CH4 selectivity than impregnation-derived 10N1FA unordered mesopores identical component, owing higher Ni dispersion larger H2 uptake. In 120 h atmospheric-pressure lifetime...
Basically super: Potassium-functionalized mesoporous γ-alumina solid superbases that have a high base strength (H−) of 27.0, well-expressed structure, and which are efficient in the isomerization 1-hexene synthesized by one-pot method. The success this method can be ascribed to flexible application K2CO3 as pH adjustor close control calcination process (see picture).

Direct generation of superbasicity on mesoporous silica SBA-15 was realized by tailoring the host-guest interaction, and calcium species were selected as guest in modifying SBA-15. The results show that could be homogeneously distributed surface Because decomposition supported nitrate apparently easier than bulk one. Surprisingly, nitrates modified (CaNS) samples exhibited with good preservation mesostructure after activation, differing from potassium loaded displayed weak basicity collapsed...
