A simple and efficient process for smallscale cleaning of poorly liberated, difficulttowash lowrank coal. Energy Sources, Part A: Recovery, Utilization.. ABSTRACT Low rank coals are often characterized by high amounts of ash forming and sulfurbearing minerals, poor liberation characteristics, and difficult washability properties. Low ...
Coal preparation is a stage in the coal supply chain that follows mining but precedes shipment to the final end user. For many operations, runofmine coal consists of a composite mixture of carboniferous material and various noncoal impurities, such as rock, shale, clay, and water. Coal preparation, also denoted washing, cleaning, processing ...
During mining, processing and utilization of coal, the environment is exposed to piles of coal, coal gangue and coal ash, which have human health concerns. Coal and coal gangue samples were obtained from a coal mining company located in Southern Province, Sinazongwe District, Zambia. The main objective of this research was to determine the level of heavy metals in coal gangue and coal from ...
Some coal deposits in Nigeria were assessed through geochemical Rock Eval pyrolysis, organic petrology and combustibility studies to characterize them and to determine their suitability as an energy source. The following correlations were obtained. Rock Eval hydrogen indices (HI) correlate proportionally with the petrographical liptinite content; oxygen indices (OI) correlate proportionally ...

The coal beneficiation plants using wet processes are named as Coal washeries. For raw coal fines of mm, the difference in surface property is utilized since conventional gravity dependent processes are inefficient for this size range. The commercial processes of coal beneficiation are based on the differences in some physical properties ...

of CCUS in mitigating climate impacts of CO 2 in the atmosphere. CCUS technology is capable of capturing CO 2 emissions from stationary and large industrial processes, such as power generation. Some of the captured CO 2 can be utilized for commercial purposes, such as EOR, while the remaining CO 2 is stored in a way that isolates it from the primary flow of the Earth's carbon cycle (Al ...
To update the methods used to provide clean and efficient conversion of coal, it is required to explore forward leading technology for the modern coal chemical industry, as shown in Fig. approaches include machinelearning technology for the efficient design and development of catalysts (Han et al., 2017); high value, highend, differentiated product production and processing technology ...
After the preenrichment process, a coal concentrate (% ash, % total sulfur, and 3350 kcal/kg calorific value) was obtained with a % yield of coal using a 44 mm hydrocyclone.
In this study, the coal gangue collected from Jungar coalfield contains 437 ppm of lithium, which is significantly higher than the average content of coal ( ppm) in China. Lithium extraction from the coal gangue was systematically investigated via the integrated process of roasting and acid leaching with the mechanism analysis.
Coal is a widely used energy source, but it also poses serious threats to human health. This article reviews the current literature on the impacts of coal combustion, mining, and utilization on various aspects of human health, such as respiratory, cardiovascular, neurological, and reproductive systems. It also discusses the potential strategies to mitigate these impacts and the challenges for ...
The conditions were identified for the efficient use of coal and oil processing waste as part of composite fuels. The relative fuel effective utilization factor of wastederived fuel mixtures in different states ranged from to It is maximal for fuels in the slurry state. The obtained data has been compared with the results of other ...
Utilization of coal in the current energy sector requires implementation of highlyefficient technologies to meet the dual targets of increased energyefficiency and reduced carbon footprint. Efforts are being made to develop gasification systems with lower unit emissions of carbon dioxide and other contaminants, capable of handling various feedstocks and flexible in terms of products ...
Both fossil and renewable fuel sources are used widely to produce electricity around the globe. The dependency on fossil fuels for energy leads to the depletion of reserves and various forms of pollution. Coal fly ash (CFA) is one of the most burning issues in the whole world due to its large amount of production in thermal power plants. Every year a million tons (MTs) of CFA are generated ...
