Fine coal (− 6 mm) cleaning in a dry way becomes more important with the extensive deployment of mechanized mining and progressively serious water shortage, especially North-West China. In this paper, we attempted to use segregation vibrated gas-fluidized bed dissimilar particles provide solution problem. The effects several factors including superficial air velocity, height, vibration intensity fluidizing time on performance were experimentally studied. bubble-driven jigging mechanism was...
Coal is one of the most important primary energy sources all over world. One clean-coal technologies coal preparation, and dry-coal beneficiation plays an increasingly role with increasing shortage water. A novel air dense medium fluidized bed (ADMFB) separator developed by China University Mining Technology, magnetic powder fine acting as heavy medium, has advantages uniform stable density, low cost, high reliability. The world's first modularized based on ADMFB was established, realizing...
Pyrite in fine coal was heated selectively by microwave energy to strengthen its magnetism this study. Then, the inorganic sulfur (−0.5 mm) removed using a 2 T strong magnetic roller separator. The migrating regulation of organic sulfur-containing groups and harmful elements analyzed employing energy-intensive process. As treatment time increased, infrared absorption peaks compound were as follows: swing vibration peak C–S −CH2SH structure, sulfone-based (O═S═O) asymmetric stretching peak,...
A Ce-doped Fe–Mn magnetic sorbent (Fe6Mn0.8Ce0.2Oy) was developed using the coprecipitation method. The effects of O2, H2O, flue gas temperature, SO2 concentration, and Ce doping on tolerance Fe6Mn0.8Ce0.2Oy for mercury removal were explored in a fixed-bed system. Combined with temperature-programmed desorption (Hg-TPD) X-ray photoelectron spectroscopy (XPS) analysis, mechanism by presence analyzed. results show that is promising circulating high tolerance. significantly enhances protecting...
The raw material for smelting brown corundum is high-quality bauxite. As the quality of bauxite decreases, main impurity, silicon content, increases, which affects product and energy consumption. Additionally, process produces a significant amount fly dust (BCFD) with low utilization rate, resulting in resource wastage. In order to utilize low-quality BCFD, this article proposes method “roasting-alkali leaching.” Through mixed desilication, impact alkali leaching factors on desilication...
Abstract As a key reaction in water electrolysis and fuel cells, the oxygen evolution (OER) involves sluggish four‐electron proton transfer process. Understanding OER pathways kinetics is critical for designing efficient electrocatalysts. In this study, through density functional theory (DFT) calculations, it demonstrated that incorporation of Gd into Fe‐doped NiO elevates O 2 p band center generates more unoccupied states. Furthermore, promotes formation vacancies, which, together, enhance...
The bed expansion height serves as a macroscopic representation of the efficiency with which vibrational energy is transmitted within pulsed fluidized beds. Due to its complex nonlinear characteristics, further research needed explore fluidization mechanisms in beds and identify effective predictive models for ratios. This work evaluates analyzes capabilities established based on theoretical learning, well three machine learning methods. Additionally, dimensionless numbers are introduced...
Fine coal dry separation technology has been one of the international research hotspots in field preparation. This article proposes shallow bed dense-phase gas–solid fluidized to remove gangue from high ash fine coal. According criterion center pressure drop, CP value can be finally reduced by reducing height, H, decrease ΔPB, under condition a fixed gas distributor ΔPD. A uniform and stable density was formed. The medium 33% particles showed better performance −6+3 mm, −3+2 −2+1 mm than...
