Low energy efficiency and high emissions of coal utilization. As a highcarbon energy source, coal will inevitably bring about carbon emissions during the process of utilization. China's CO 2 emissions per unit of GDP are much higher than those of developed countries, and its total emissions now rank first in the world. The energy ...
An understanding of the effect of maceral composition during coal conversion process is essential as the variation in its physical and chemical properties influences coal utilization technologies. High yields of volatile matter can be achieved from liptinite upon heating making it ideal for bitumen and tar production (Falcon and Ham 1988).

• Coal Preparation is a major contributor to the economic and environmental viability of coal as a source of fuel for thermal power generation, • An unavoidable fact is that the second largest populated country in the world, India, is rich in coal resources and will further develop its utilization for the generation of electricity,
Refusederived fuel (RDF) from municipal solid waste (MSW) is an alternative fuel (AF) partially replacing coal/petcoke in a calciner/kiln of cement plant. The maximum thermal substitution rate (TSR) achieved through RDF is 80100% in the calciner, while it is limited to 5060% in the kiln burner. Different AF precombustion technologies, advancements in multichannel burners, and new ...
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 ...
The key focus of the present study is to review the literature related to the utilization of untreated and treated coal mining and processing wastes in the construction of sustainable roads. Following a suitable Preferred Reporting Items (PRISMA) framework for systematic review, 67 records are considered for the qualitative analysis.

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.
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 ...
Large amounts of lead slag are produced during the production of primary lead and secondary lead. Considering lead concentrate smelting as an example, a primary lead smelting system production of 1 t of lead will discharge 7100 kg of lead slag (Hou, 2011).At the secondary lead recycling process, for each ton of metallic lead produced, 100350 kg of slag are generated (Kreusch et al., 2007).
