Coal gasification fine slag (FS) is a by-product of coal with significant potential for resource utilization. However, the low recovery rate residual carbon greatly restricts its utilization and harmless disposal. In this paper, spiral separator was used to recover FS, followed by use oil agglomeration separation technology enhance selection concentrate. The mechanism process analyzed through EDLVO theoretical calculation. Finally, ecological risk metal element speciation in separated...
In order to exploit the deep underground space, construction of ultra-deep excavation in Shanghai is growing rapidly. multi-aquifer strata, excavations typically require dewatering confined aquifers ensure engineering safety. However, existing studies have seldom conducted in-depth analysis on influence soil parameters and measures deformation retaining structures. this study, a three-dimensional hydro-mechanical numerical model was developed evaluate performances foundation pit. The...
<div class="section abstract"><div class="htmlview paragraph">Three-way catalysts (TWCs) containing significant amounts of precious metals are commonly employed to purify exhaust emissions (CO, NO<sub>x</sub>, and THC) from gasoline-powered vehicles. A critical factor contributing TWC degradation is the sintering these metals. Maintaining appropriate particle size distribution essential for optimal catalyst performance. In this study, palladium (Pd) nanoparticles with...
CRTS III (China Railway Track System) slab track is a typical multi-layer composite structure. Door-shaped rebar an important connecting component. Studying its service characteristics crucial for disease prevention and control. To investigate the mechanical properties of door-shaped under multi-factor coupling, three-dimensional finite element model was developed validated with full-scale tests. Then, considering initial defects self-compacting concrete (SCC), interlayer cracks other...
The heat flux density of solar radiation, received by each surface a double-block ballastless track bed slab, is closely related to its alignment and geographical latitude. In this work, temperature field analysis model based on experimental data, the theories boundary transfer established CRTS-I structure using ABAQUS finite element software investigate influence different alignments latitudes field. horizontal vertical gradients ballast plate were found be in most adverse conditions when...
In this study, in situ experiments were conducted to study the changing characteristics of lateral and longitudinal resistance a ballast bed, three-dimensional model for bed sleeper was constructed based on discrete-element method. The effects such as gravel grading, depth, angle shoulder slope, width, among others, studied. results suggest that (1) increases with widening within size distribution limits, satisfies specification; (2) an increase depth specifications greater than 150 mm; (3)...
A high-speed wheel/rail finite element model is developed to focus on the non-steady-state rolling contact. The contact solved based surface-to-surface algorithm, and explicit method used simulate dynamic Considering track–vehicle coupling system dynamics geometric nonlinearities, short wave rail corrugation under high-frequency vibration influence of train passing frequency are studied. can be process wheel/rail. After initial load condition, state tends stable in a period time. causes...
Early childhood interventions played a critical role in improving child development impoverished contexts. Combined nutrition and psychosocial stimulation (CNPSI) have shown more benefits than stand-alone supplemental (SNI) many developing countries. Based on cluster randomized controlled trial rural northwestern China, this study tested alternative theory-driven hypotheses regarding how primary caregiver's education family income may moderate the CNPSI's effects growth environment...
