Abstract As the unique power entrance, pantograph–catenary electrical contact system maintains efficiency and reliability of transmission for high-speed train. Along with fast development railways all over world, some commercialized lines are built covering remote places under harsh environment, especially in China; these environmental elements including wind, sand, rain, thunder, ice snow need to be considered during design system. The includes pantograph, wire interface—pantograph slide....
Hydrodeoxygenation (HDO) of lignin derivatives at room-temperature (RT) is still challenge due to the lack satisfactory activity reported in previous literature. Here, it successfully designed a Pd/UiO-66-(COOH)
Nondestructive testing (NDT) techniques are widely used for inspection and evaluation of conductive materials. However, a single physical mechanism sensing cannot simultaneously satisfy multiple requirements. In this article, we propose hybrid transducer based on magnetic flux leakage (MFL) electromagnetic acoustic (EMAT) synchronous detection surface internal defects. the proposed transducer, both MFL EMAT share common field. The circuit characteristics principles fully exploited, field...
A novel process path is proposed to produce glycolic acid (GA) from CO2 as the feedstock, including capture, power-to-hydrogen, hydrogenation methanol, methanol oxidation formaldehyde, and formaldehyde carbonylation units. The bottlenecks are discussed perspectives of carbon utilization, emissions, total site energy integration, techno-economic analysis. utilization ratio 82.5%, capture unit has largest percentage discharge in utilization. Among indirect emissions each unit, proportion...
The screening of high-efficiency and low-energy consumption absorbents is critical for capturing SO2. In this study, with better performance are screened based on mechanism, model, calculation, verification, analysis methods. acidity coefficient (pKa) values ethylenediamine (EDA), piperazine (PZ), 1-(2-hydroxyethyl)piperazine (HEP), 1,4-bis(2-hydroxyethyl)piperazine (DIHEP), 1-(2-hydroxyethyl)-4-(2-hydroxypropyl)piperazine (HEHPP) calculated by quantum chemical A mathematical model the SO2...
Abstract Efficient low‐temperature hydrodeoxygenation (HDO) of lignin derivatives to produce biofuels and high value‐added chemicals is still challenge. Here, we have constructed a active stable 0.2 wt.% Pd/MS‐HZSM‐5(30) catalyst, 94.7 % yield 2‐methoxy‐4‐methylphenol (MMP) can be achieved in HDO vanillin (VAN, typical platform molecule derivatives) under milder reaction conditions (60 °C, 5 h, molar ratio VAN/Pd=1200, water phase), outperforming the most works reported recently. Detailed...
In this study, crumpled graphene balls (CGB), a kind of nano-material, was used as an additive to improve the tribological properties base oil. Nano-magnesium silicate hydroxide (MSH)/CGB composites were prepared by ultrasound-assisted liquid-phase exfoliation. The loading MSH significantly increased number pleats and reduced lamellar thickness CGB. Then, in order compatibility with oil, MSH/CGB decorated oleic acid stearic get modified lipophilic (ML-MSH/CGB). ML-MSH/CGB characterized...
In in situ-generated proppant fracturing technology without injection, the distribution of flow pattern two-phase fluid fracture determines concentration particles formed by phase change different positions. Therefore, study a is great significance to reveal formation mechanisms patterns and guide on-site implementation technology. This paper establishes mathematical model for fluids fractures based on their physical properties presents numerical experiments under conditions injection...
Perfluoroisobutyronitrile (C<sub>4</sub>F<sub>7</sub>N) has the potential to replace SF<sub>6 </sub>due its excellent environmentally friendly dielectric properties, and received extensive attention at home abroad. C<sub>4</sub>F<sup>7</sup>N a low liquefaction temperature, so it is necessary mix with low-boiling gas during application. Among them, C<sup>4</sup>F7<sub>N</sub>/CO<sub>2</sub> mixed performance, but insulation capacity closely related C<sub>4</sub>F<sub>7</sub>N content....
At present, solid waste is developing towards high value utilization. Premixed coal ash and incineration were introduced into temperature blast furnace slag as admixture.
