NiWO(4) nanoparticles have been facilely synthesized by a hydrothermal approach, and used as catalyst for the hydrodesulfurization of thiophene its derivative 4,6-dimethyldibenzothiophene, showing significantly higher activity than commercial NiW/Al(2)O(3).
Multiple sclerosis (MS) is the common neurological disorders in young adults, which affects central nervous system myelin or oligodendrocytes and results disability. This study aimed to identify key miRNAs blood of patients MS for better understanding underlying mechanisms MS.The publicly available Gene Expression Omnibus data-sets were performed integrated analysis. miRNA expression mRNA analyzed whole samples from with healthy controls by microarray analysis, Ontology enrichment analyses,...
SO<sub>4</sub><sup>2−</sup> anchors to a NiMo/γ-Al<sub>2</sub>O<sub>3</sub> catalyst, weakening the metal–support interactions, inhibiting MoS<sub>2</sub> aggregation, increasing number of Ni–Mo–S sites, and thus improving its activity stability.
Hydrocracking has become the main technology for producing diesel fuel in many refineries, key process to meeting new product specifications as environmental regulations transportation fuels more stringent. The efficacy of hydrocracking catalyst is a pivotal determinant reaction performance. This study leveraged high-throughput experimentation closely examine impact support properties on both catalytic activity and selectivity middle distillates. findings show that catalyst's mainly...
The preparation of low‐dimensional transition metal disulfides (MS2, M = Mo, W) via ultrasonication‐assisted liquid‐phase exfoliation from mineral bulk‐MS2 is proven to be advantageous in terms sulfurizing reagent‐free conditions and operational safety. Nevertheless, mechanical energy input insufficient effectively cut metal‐sulfur bonds form small‐sized MS2 nano‐dots. Herein, we develop an innovative strategy based on hydroxyl radicals‐mediated cutting prepare nano‐dots with lateral...
In lower rate, Li + have enough time to insert into the graphitic layer, capacity of graphite primarily determined by σ e . However, with increasing insertion/extraction will become more difficult, making mainly factor.
Hydrodesulfurization (HDS) is an important process for the production of clean fuel oil, and development a new environmentally friendly, low-cost sulfided catalyst key research in hydrogenation technology. Herein, commercial bulk MoS2 NiCO3·2NiOH2·4H2O were first hydrothermally treated then calcined H2 or N2 atmosphere to obtain Ni–MoS2 HDS catalysts with different structures. Mechanisms hydrothermal treatment calcination on structures investigated by X-ray diffraction (XRD), high-resolution...
Abstract The purpose is to study seismic response and dynamic lateral pressure of the silo wall with different storage conditions under earthquake. FEM was used conduct time history analysis silo. empty smaller than that filled silos, for latter, action, bulk sand particles had a more complex interaction, nodes displacements on columns mainly fluctuated rising. For deformation sand, it similar parabolic pattern in section, closer center greater was, farther away from was. maximum...
The origin of the active sites hydrodenitrogenation catalysts was comprehensively studied using alumina-supported MoS<sub>3</sub>nanoparticles (NPs) as a novel precursor.
A simple but efficient strategy to improve the ability of adsorptive denitrogenation (ADN) MIL-101(M101) was studied by in situ encapsulation phosphomolybdic acid (PMA) and subsequent purification as-synthesized product NH4F solution. After treatment, vast majority PMA removed, loss organic ligand (BDC) observed, fluorination hydroxyl group M101 structure occurred. The ADN activities Cr-MOF matrix composites before after were detail. rest interacts strongly with assists activity....
Fe 2 O 3 accelerates the polycondensation of asphalt molecules, consumes excessive H and breaks intact carbon layer, which weakened π–π interactions, finally enhances formation amorphous carbon.
Spent hydrodemetallization (HDM) catalysts were collected from pilot-scale reactors with different time-on-stream, and they treated an extraction or regeneration method for further investigation. The fresh, spent, regenerated samples characterized systematically. Their catalytic performances assessed using model molecules Kuwait atmospheric residue as the reactants. Compared conventional NiMo/Al2O3 catalysts, deposited metal sulfides had a notable increase in their HDM activity but obvious...
In this present work, a new kind of sulfurized hydrodesulfurization catalyst was synthesized via the hydrothermal treatment MoS2, NiCO3·2Ni(OH)2·4H2O, and Al2O3 precursors, followed by annealing under H2 atmosphere, which does not require sulfurization process compared to traditional preparation methods. The influence temperature type precursor on interactions between MoS2 were studied using X-ray fluorescence spectroscopy, diffraction, N2 adsorption–desorption, Raman photoelectron...
TiO2-Al2O3 supports with different incorporation methods of titania were synthesized via three methods: impregnation (TA-I), co-precipitation (TA-CP), and co-precipitation–hydrothermal treatment (TA-HT). And the NiMoP catalysts prepared on corresponding evaluated for hydrodesulfurization (HDS) reactions. The results demonstrated that Ti atoms in TA-I are attached to alumina through hydroxyl groups, while TA-CP TA-HT can be dispersed skeleton. Variations modes TiO2 affect support properties,...
