Thirty-six coal bench samples from Coal Seam 6 and 13 parting 5 layers were taken the Guanbanwusu Mine, Jungar Coalfield, Inner Mongolia, analysed by optical microscopy, A scanning electron microscope in conjunction with an energy-dispersive X-ray spectrometer (SEM-EDX) analysis, powder diffraction (XRD), inductively coupled plasma mass spectrometry (ICP-MS) fluorescence spectrometric (XRF) techniques. The results indicate that average Li content are 264 ppm 1320 or 0.28% 2 O ash, indicating...
Coals are a major source of pollution in certain parts the world due to mining, coal combustion, and disposal fly ash. The recovery valuable rare metals from coals or coal-processing byproducts is promising way utilise these traditional resources economically, efficiently an environmentally friendly way. Lithium, highly interesting metal, has been found dispersed even anomalously enriched deposits, potentially extractable. This paper presents review geochemical investigations on Li-bearing...
Lithium is an important energy metal. Its concentrations in coals have been studied by many geologists. average content only 14 mg/kg the of world. has never reported as a coal associated deposit before. In order to study Chinese coals, 159 and gangue samples were taken from six mines determined ICP-MS minerals identified X-ray powder diffraction. The results indicate that Li contents Antaibao Coal Mine reached industry grade deposits. Tongxing Mine, floor rock independent lithium Main are...
Natural gas, in its migration from source rocks to release zones may travel a long distance and change the geochemical characteristics of which it flowed through. In order study evidence natural gas migration, 24 samples were taken different Ordos Basin, China. Five them are (dark sandstone samples), 17 bleaching (bleaching two non-release (background samples). These analyzed by organic inorganic methods. The results GC traces ICP-MASS indicate that three show characteristics. releasing be...
In this study, three triphenylamine-based hexaarylbiimidazole (HABI) derivatives featuring different numbers of methoxy groups (none for <bold>HABI1</bold>, two <bold>HABI2</bold>, and four <bold>HABI3</bold>) have been synthesized.
Wildfire episodes have implications on reshaping life earth. This article emphasises the fate and facts of wildfire during Permo-Carboniferous coal-forming period. Charcoal refers to an incomplete combustion or carbonised solid residue plant material. Inertinite (group coal macerals) is synonym charcoal at microscopic scale but its origin debatable. Moreover, inertinite has been used predict levels atmospheric oxygen, as it forms when material subjected intense heat oxygen-rich conditions....
A novel technique was developed for the recovery of lithium and aluminum from coal fly ash using a combination pre-desilication an intensified acid leaching process. The main components high-aluminum were found to be Al2O3 SiO2, Al/Si ratio increased 1.0 1.5 after desiliconization. content met national recycling standards. optimal conditions, under which efficiencies 82.23% 76.72%, respectively, as follows: 6 mol/L HCl, 1:20 solid liquid ratio, 120 °C 4 h. During hydrochloric pressure...
Abstract: Total 138 coal samples and 14 parting were taken from the No. 6 Seam of Jungar Coalfield, Inner Mongolia. These analysed by optical microscopy, sequential chemical extraction procedure (SCEP), inductively coupled plasma mass spectrometry (ICP–MS), X–ray powder diffraction (XRD), scanning electron microscope in conjunction with an energy–dispersive spectrometer (SEM–EDX) analysis. The results indicate that Li contents have reached industrial grade associated deposit, total reserves...
Pyrolysis characteristics and mechanism of tobacco stem were studied by pyrolysis coupled with gas chromatography/mass spectrometry (Py-GC/MS), thermogravimetric analyzer Fourier transform infrared spectrometry, mass (TG-FTIR TG-MS) techniques.The composition evolved volatiles from fast was determined Py-GC/MS analysis, the evolution patterns major products investigated TG-FTIR TG-MS.Py-GC/MS data indicated that furfural phenol in low temperature pyrolysis, these generated depolymerization...
Gallium is widely used in electronic industry and its current price about 500 US dollars pro kilogram. It has been found that contents are very high Permo-Carboniferous coal of China. In order to look for valuable associated gallium deposits coal, 177 samples were determined by using inductively coupled plasma-mass spectrometry (ICP-MS) the data 873 from Chinese coalfields collected. The results show average concentration coals 15.49μg·g −1 . There two types coals: One type enriched an ore...
Rare earth elements (REEs) can provide lots of information relevant to the evolution source rocks, depositional environment, and epigenetic tectonic activity. In this study, 14 bench samples (including 11 coals, 1parting, 1roof 1floor) No. 2 coal seam from Huangling Mine, Huanglong Coalfield, Ordos Basin, China were collected study REE geochemistry. The average concentration REEs is 44.03 μg/g, it lower than those in coals Chinese world coal. are enriched light LREEs-HREEs have been highly...
A numerical study of two-phase flow inside the nozzle holes and issuing spray jets for a multihole direct injection gasoline injector has been presented in this work. The geometry is representative Spray G nozzle, an eight-hole counterbore injector, from engine combustion network (ECN). Simulations have carried out fixed needle lift. effects turbulence, compressibility, noncondensable gases considered Standard k–ε turbulence model used to turbulence.

Abstract Total of 23 bench samples were taken from the No. 7 Coal Iqe Coalfield, Qinghai Province, China, following Chinese Standard Method GB/T 482–2008 (2008). These analyzed by powder X‐ray diffraction (XRD), inductively coupled plasma mass spectrometry (ICP‐MS) and fluorescence (XRF). The results indicate that belongs to a low rank ( R o,ran =0.659%) high‐ash coal (40.54%). Compared common world low‐rank coals, contains anomalous concentrations rare metal elements, rare‐scattered...
