Various metal-modified HMOR catalysts for the carbonylation of dimethyl ether (DME) were prepared by ion exchange with Cu, Ni, Co, Zn, or Ag. The characterized Brunauer–Emmett–Teller method, X-ray diffraction measurements, transmission electron microscopy, photoelectron spectroscopy, nuclear magnetic resonance temperature-programmed desorption ammonia, and oxidation. We found that pore structure mordenite (HMOR) was well maintained metal species highly dispersed on zeolite. On subjected to...
Depth-of-field extension and accurate 3D position location are two important issues in digital holography for particle characterization motion tracking. We propose a method of locating the axial positions both opaque transparent objects reconstructed field wavelet domain. The spatial–frequency property image is analyzed from viewpoint point spread function inline holography. decomposed into high- low-frequency subimages. By using variance gradient subimages as focus metrics, depth-of-field...
Brønsted acid sites and reducibility are crucial for a vandaia catalyst in selective catalytic reduction of NO reaction. Alkali oxides poisonous to vanadia catalyst. Theoretical chemistry computations experiments were performed study the reaction alkali with afterward influence left on Both NH3 adsorption neutralization by proceed sites. computation density functional theory shows that oxide is more exothermic than adsorption. The easy consumption results transformation surface nature...
Methyl acetate (MA) hydrogenation to ethanol was investigated over SBA-15 supported copper (Cu/SBA-15) catalysts prepared by different methods, including impregnation, deposition precipitation, and homogeneous precipitation. The were characterized means of the Brunauer–Emmett–Teller method, X-ray diffraction, transmission electron microscopy, temperature-programmed reduction photoelectron spectroscopy. Of three catalysts, it found that Cu/SBA-15 catalyst precipitation method has smallest...
An advanced single-phase reaction system consisting of water–DMOE solvent and AlCl<sub>3</sub> could be used efficiently economically in HMF production.
To promote the effective utilization of different varieties low-calorific gas mixtures in a porous media burner, combustion behaviors three typical two-layer burner are simulated with two-energy and one-dimensional transient model. The equivalence ratio inlet velocity kept constant. A baseline simulation for is presented, partial results compared against experimental measurement axial temperatures emission levels. parametric study conducted on conductivity convective coefficient up-...
Hydrodeoxygenation (HDO) of lignin-derived phenolics is promising to produce high-value-added chemicals and liquid fuels. As a strong oxophilic support, Nb2O5 maintains high catalytic activity for the deoxygenation oxygen-rich reactants, while few studies have clarified influence crystal structures on reactivity. In this study, supports with three (pseudohexagonal-TT, orthorhombic-T, monoclinic-H) were successfully prepared used HDO after loading bimetal Ni Co. The structural properties...
Coal blending is an effective way to organize and control coal ash fusibility meet different requirements of Coal-fired power plants. This study investigates three eutectic processes explains the mechanism how affects fusibility. The blended ashes were prepared by hand-mixing two raw at five ratios, G:D = 10:90 (G10D90), G:D= 20:80 (G20D80), 30:70 (G30D70), 40:60 (G40D60), 50:50 (G50D50). samples heated 900 °C, 1000 1100 1200 1300 °C in reducing atmosphere. XRD SEM/EDX used identify mineral...
A fundamental study was carried out on the high-temperature zone flow resistance during iron ore sintering. In present work, firstly, quartz sand used to replace ores investigate impact of temperature if bed structure has no change; then a three-layer explore primary factors controlling for airflow. The where above 700°C is defined as high zone. High-temperature depends sinter and which related melt volume, properties, voidage, drive force thickness. new model can suggest established by...
