The structural features and reduction-induced evolution of Ni/Ce1–xZrxO2 catalysts for the methanation carbon oxides were investigated. prepared by impregnation technique investigated ex situ in X-ray diffraction (XRD) analysis, atomic pair distribution function (PDF) transmission electron microscopy, photoelectron spectroscopy (XPS), temperature-programmed reduction H2. main part nickel was established to exist on support surface as bulk NiO Ni0 nanoparticles as-prepared reduced under...
Ethanol is one of the promising sources hydrogen (synthesis gas), including in various energy applications. The production synthesis gas from ethanol possible ways, for example, such as steam and steam-air conversion, which are endothermic thermoneutal reactions, respectively. Control management heat mass transfer during occurrence these reactions an important task, can be solved through use catalysts on heat-conducting metal substrates. This paper presents results a study physicochemical...
Реакции паровой и паровоздушной конверсия бутанола позволяют получать синтез-газ, который может быть использован в качестве сырья ряде химических приложений или топлива для твердооксидных топливных элементов. Эффективность протекания этих реакций значительной мере определяется теплообменом. В случае эндотермической реакции - конверсии метана, необходимо обеспечить передачу тепла от стенок реактора внутрь слоя катализатора. При конверсии, являющейся термонейтральной слабо экзотермической...
The structure of copper oxide species in Cu/ZrO2 catalysts with monoclinic zirconia as a support was studied. various loadings (3–40 wt % Cu) prepared by impregnation technique were characterized using N2O titration, X-ray diffraction (XRD) analysis, radial distribution function (RDF) electron density, and high-resolution transmission microscopy (HRTEM). It established that the contained highly dispersed CuO particles along large ones. Geometrical similarity between ZrO2 structures favors...
Despite the fact that metastable aluminum oxides are actively used in industry, there is a discrepancy literature regarding their crystal structure. All this leads to difficulties data interpretation and, as consequence, classification problems. This work aimed at solving these tasks. The main features of powder X-ray diffraction typical samples three Al2O3 polymorphs (γ-, χ-, η-) analyzed. Specifics and fundamental differences scattering relationship with structural organization...
Among the known synthesis procedures and reagents for unsupported Ni–Mo–W catalysts, there is no consensus about optimal preparation conditions of their precursors. In present work, precursors were prepared via three techniques—hydrothermal synthesis, precipitation method spray drying—after complex compounds in solution. studied by XRD analysis, SEM methods, Raman UV-vis spectroscopies XPS measurements used hydrotreatment straight-run gasoil. Precursors hydrothermal contain particles with...
Two sets of silica-supported nickel phosphide catalysts with a content about 2.5 and 10 wt % Ni/P molar ratio 2/1, 1/1 1/2 in each set, were prepared by way temperature-programmed reduction method using (Ni(CH3COO)2) ((NH4)2HPO4) as precursor. The NixPy/SiO2 characterized chemical analysis N2 physisorption, XRD, TEM, 31P MAS NMR. Methyl palmitate hydrodeoxygenation (HDO) was performed trickle-bed reactor at 3 MPa 290 °C LHSV ranging from 0.3 to 16 h−1. found affect the phase composition, POx...
The effect of support nature, SiO2 and γ-Al2O3, on physicochemical catalytic properties nickel phosphide catalysts in methyl palmitate hydrodeoxygenation (HDO) has been considered. Firstly, alumina-supported prepared by temperature-programmed reduction method starting from different precursors (phosphate–Ni(NO3)2 (NH4)2HPO4 or phosphite–Ni(OH)2 H3PO3) were compared using elemental analysis, N2 physisorption, H2-TPR, XRD, TEM, NH3-TPD, 27Al 31P MAS NMR techniques experiments. mixture phases...
The Ni2P/SiO2 catalyst, which was prepared by in situ temperature-programmed reduction and the mixture with inert (SiC, SiO2) or acidic (γ-Al2O3) material studied methyl palmitate hydrodeoxygenation (HDO). Methyl HDO carried out at temperatures of 270–330 °C, H2/feed volume ratio 600 Nm3/m3, H2 pressure 3.0 MPa. diluted γ-Al2O3 showed a higher activity than catalyst SiC SiO2. conversion increased significantly presence most probably due to acceleration acid-catalyzed reaction ester...
