Maceral Types and Quality of Coal in the Tuli Coalfield: a Case
applied sciences Article Maceral Types and Quality of Coal in the Tuli Coalfield: A Case Study of Coal in the Madzaringwe Formation in the Vele Colliery, Limpopo Province, South Africa Elelwani Denge * and Christopher Baiyegunhi Department of Geology and Mining, University of Limpopo, Private Bag X1106, Sovenga 0727, South Africa; [email protected] * Correspondence: [email protected] Featured Application: Authors are encouraged to provide a concise description of the specific application or a potential application of the work. This section is not mandatory. Abstract: The Madzaringwe Formation in the Vele colliery is one of the coal-bearing Late Palaeozoic units of the Karoo Supergroup, consisting of shale with thin coal seams and sandstones. Maceral group analysis was conducted on seven representative coal samples collected from three existing boreholes—OV125149, OV125156, and OV125160—in the Vele colliery to determine the coal rank and other intrinsic characteristics of the coal. The petrographic characterization revealed that vitrinite is the dominant maceral group in the coals, representing up to 81–92 vol.% (mmf) of the total sample. Collotellinite is the dominant vitrinite maceral, with a total count varying between 52.4 vol.% (mmf) and 74.9 vol.% (mmf), followed by corpogelinite, collodetrinite, tellinite, and pseudovitrinite with a Citation: Denge, E.; Baiyegunhi, C. count ranging between 0.8 and 19.4 vol.% (mmf), 1.5 and 17.5 vol.% (mmf), 0.8 and 6.5 vol.% (mmf) Maceral Types and Quality of Coal in the Tuli Coalfield: A Case Study of and 0.3 and 5.9 vol.% (mmf), respectively.

The Bedford Cannel Coal Creators: Orton, Edward, 18

In the hills of southern Jefferson and northern Bedford town- ships, Coshocton County, Ohio, is found a coal vein, to the struc- ture and possible economic importance of which I wish to call attention. It is most widely known as the Bedford Cannel, the largest tracts of it being found in Bedford Township. Though there are, in nearly all the coal-bearing counties of the State, small local deposits of cannel coal, yet only six places assume sufficient importance to be called cannel producing dis- tricts. Five of these are located respectively at Flint Ridge, Lick- ing County; Millersburg, Holmes County; Sand Run, Hocking County, Milton Township, Jackson County, and in Eastern Colum- biana County. The first two deposits are of very small impor- tance; the Darlington Cannel, of Columbiana County, is so inferior to that just over the Pennsylvania line that it assumes no impor- tance as yet, and the developments at Sand Run and Jackson County are of about equal and growing importance. The sixth and last deposit, the Bedford Cannel is the largest, and, probably, the best body of cannel in Ohio; but its remoteness from railroad travel has prevented its reputation or use from extending far. -
High Calorific Value Coal Turkish and Global Outlook
High calorific value coal Turkish and global outlook October 2014 2 Executive Summary Despite the fact that coal has notorious perception due to its impacts on the environment, it’s not possible to neglect its share in the global energy supply. Especially, in emerging markets with ever growing energy demand, cost and eligibility advantages bring coal into prominence. When a coal consumption analysis is conducted, it is evident that electricity and heat generation sector maintained its leadership with more than 3.8 billion tonnes in 2012. This situation can be seen in Turkey as well. Installed capacity of imported coal PPs in Turkish Uygar Yörük electricity market has passed 3.9 GW by the end Energy & Resources Industry Leader of the 2013. On account of increasing Turkish Partner electricity demand and economic advantages of imported coal, it wouldn’t be wrong to expect that imported coal PPs will show significant growth. In the first seven months of On the other side, all locations available to 2014, additional installed capacity of 950 MW imported coal power plants are already held connected to the grid. After the natural gas by investors and some of these projects will be investment boom in 2011, Turkish electricity naturally driven out of the competition. market has a new tendency to imported coal power plants. When global coal market is analysed, trends like China’s growing coal demand, shale gas Uncertainties related to natural gas power plants impact on coal prices and carbon policies and unexpected delays in lignite projects lead can be defined as major indicators that have investors to hard coal as a relatively more eligible determining role on coal pricing. -
AP-42, Vol. I, CH1.1 Bituminous and Subbituminous Coal Combustion
1.1 Bituminous And Subbituminous Coal Combustion 1.1.1 General Coal is a complex combination of organic matter and inorganic mineral matter formed over eons from successive layers of fallen vegetation. Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite. Coal rank depends on the volatile matter, fixed carbon, inherent moisture, and oxygen, although no single parameter defines a rank. Typically, coal rank increases as the amount of fixed carbon increases and the amount of volatile matter and moisture decreases. Bituminous coals are by far the largest group and are characterized as having lower fixed carbon and higher volatile matter than anthracite. The key distinguishing characteristics of bituminous coal are its relative volatile matter and sulfur content as well as its slagging and agglomerating characteristics. Subbituminous coals have higher moisture and volatile matter and lower sulfur content than bituminous coals and may be used as an alternative fuel in some boilers originally designed to burn bituminous coals.1 Generally, bituminous coals have heating values of 10,500 to 14,000 British thermal units per pound (Btu/lb) on a wet, mineral-matter-free basis.2 As mined, the heating values of typical U.S. bituminous coals range from 10,720 to 14,730 Btu/lb.3 The heating values of subbituminous coals range from 8,300 to 11,500 Btu/lb on a wet, mineral-matter-free basis2, and from 9,420 to 10,130 Btu/lb on an as-mined basis.3 Formulae and tables for classifying coals are given in Reference 2. -
Coal As an Abundant Source of Graphene Quantum Dots
ARTICLE Received 8 Jul 2013 | Accepted 14 Nov 2013 | Published 6 Dec 2013 DOI: 10.1038/ncomms3943 Coal as an abundant source of graphene quantum dots Ruquan Ye1,*, Changsheng Xiang1,*, Jian Lin2, Zhiwei Peng1, Kewei Huang1, Zheng Yan1, Nathan P. Cook1, Errol L.G. Samuel1, Chih-Chau Hwang1, Gedeng Ruan1, Gabriel Ceriotti1, Abdul-Rahman O. Raji1, Angel A. Martı´1,3 & James M. Tour1,2,3 Coal is the most abundant and readily combustible energy resource being used worldwide. However, its structural characteristic creates a perception that coal is only useful for pro- ducing energy via burning. Here we report a facile approach to synthesize tunable graphene quantum dots from various types of coal, and establish that the unique coal structure has an advantage over pure sp2-carbon allotropes for producing quantum dots. The crystalline carbon within the coal structure is easier to oxidatively displace than when pure sp2-carbon structures are used, resulting in nanometre-sized graphene quantum dots with amorphous carbon addends on the edges. The synthesized graphene quantum dots, produced in up to 20% isolated yield from coal, are soluble and fluorescent in aqueous solution, providing promise for applications in areas such as bioimaging, biomedicine, photovoltaics and optoelectronics, in addition to being inexpensive additives for structural composites. 1 Department of Chemistry, Rice University, 6100 Main Street, Houston, Texas 77005, USA. 2 Department of Mechanical Engineering and Materials Science, Rice University, 6100 Main Street, Houston, Texas 77005, USA. 3 Smalley Institute for Nanoscale Science and Technology, Rice University, 6100 Main Street, Houston, Texas 77005, USA. * These authors contributed equally to this work. -
