Microporous and mesoporous carbon spheres (CSs) were fabricated using resorcinol formaldehyde as precursors in the presence of Pluronic F127 porogen KOH active agent. The textural characteristic morphology characterized by scanning electron microscopy, transmission N2 adsorption/desorption techniques. played an important role for generating mesopores, while activation brought abundant micropores resulted a combined microporous structure CSs. results showed that typical sample (denoted...
Carbon electrode materials for double layer capacitors have attracted much attention, due to their low cost and abundant sources. Their specific capacitance, however, hinders the development of carbon materials. In this paper, large surface area commercial activated carbons, rich in micropores, were initially oxygen-functionalized by treatment using concentrated H₂SO₄, saturated (NH₄)₂S₂O₈, H₂SO₄/(NH₄)₂S₂O₄ mixed oxidants, respectively. The as-prepared samples analyzed N₂...
The catalysts Ni/Al 2 O 3 and CaO modified were prepared by impregnation method applied for methanation of CO . characterized N adsorption/desorption, temperature-programmed reduction H (H -TPR), X-ray diffraction (XRD), desorption (CO -TPD -TPD) techniques, respectively. TPR XRD results indicated that can effectively restrain the growth NiO nanoparticles, improve dispersion NiO, weaken interaction between Al suggested change environment surrounding adsorption thus reactants on Ni atoms be...
The effects of catalyst supports, like CNTs and Al2O3, the Ce addition on catalytic performance CO2 methanation were investigated. could increase dispersivity nickel species, which reduced more easily with CNTs-supported catalyst, promoted reduction species. Furthermore, compared Ni-Ce/Al2O3 a significant improvement for was obtained Ni-Ce/CNTs catalyst.
Effects of particle size on CH4 and CO2 adsorption desorption characteristics coals are investigated at 308 K pressures up to 5.0 MPa. The gas isotherms with sizes ranging from 250 μm 840 measured via the volumetric method, Langmuir model is used analyse experimental results. Coal found have an obvious effect coal pore structure. With decrease in process grinding, accessibility coal, including specific surface area volume, increases. Hence, smaller has higher volume. ability was highly...
Abstract This paper studied the role of O ‐containing groups over coal surface in methane adsorption. The was modified with H 2 SO 4 , (NH ) S 8 or /(NH ), respectively, to introduce functional groups, and characterized by proximate analysis, ultimate Boehm titration, X‐ray photoelectron spectroscopy (XPS) nitrogen results titration XPS indicate that there were increases terms both content oxygen quantities coals surface, especially for carboxyl. Nitrogen adsorption shows possessed higher...
The Ni/MgO and Ni-Cu/MgO catalysts were prepared by sol-gel method used as the for synthesis of carbon nanotubes thermal chemical vapor deposition. effect Cu on yield structure was investigated, effects calcination temperature reaction also investigated. synthesized materials characterized programmed reduction (TPR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM). Results showed that addition promoted nickel species, subsequently improving growth CNTs. Meanwhile, CNTs...
The effect of Ca content on the CO2 methanation performance NiCa/AC catalysts was studied in detail. addition can effectively restrain growth NiO nanoparticles and improve dispersion NiO. results showed that with a nickel 15 wt.% had better catalytic activities than pure Ni/AC, modified catalyst 10 highest activity among tested catalysts.
In this paper we investigate the influence of microstructure on CH4 adsorption behavior deep coal. The coal is characterized by N2 at 77 K, scanning electron microscopy (SEM), Raman spectroscopy, and Fourier transform infrared spectroscopy (FT-IR). adsorptions are measured 298 K pressures up to 5.0 MPa volumetric method fitted Langmuir model. results show that model fits well with experimental data, there a positive correlation surface area, pore volume, ID/IG, capacity. burial depth also...
