Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Sulfur in Illinois Coals Sulfur in its several forms is prominent among the species of mineral matter known to occur in coal. Not only is the occurrence of combined sulfur prevalent in coal, but its effects can be extremely detrimental, and some of the coals with high sulfur content are restricted in the manner in which they may be utilized. The public has become aware of several of the many problems associated With the presence of sulfur in coal with the recently increased concern for all forms of air and water pollution, including sulfur dioxide (soz) emission into the atmos phere from coal-fired boilers and acid drainage into streams from coal mines, spoil piles, and refuse dumps. Other problems associated with the presence of sulfur in coal include possible contribution to spontaneous combustion of coal in mines, in refuse piles, and in stored and stockpiled coal; the formation of boiler deposits and associated corrosion of boiler tubes; difficulties in mining and coal preparation; and the need for low-sulfur coals in the manufacture of metallurgical coke. Because of the recognition of the importance of sulfur in the utilization of coal, investigations concerning sulfur in coal have been pursued at the Illinois State Geological Survey Since its founding more than 60 years ago. One of the objectives of this Circular will be to summarize the pertinent data concerning sul fur in coal, which have been collected, and in many cases published, by members of the Geological Survey staff over that period of time. In addition, recently devel oped data cm the distribution of sulfur in Illinois coals will be discussed. The 1n formation from the chemical analyses of the coal samples in which we are interested has been put into a form whereby computer processing is possible, and this enables us to analyze much more completely this large amount of data. Except where specifically stated to the contrary, all data from chemical analyses discussed in this paper were obtained from analyses of face-channel samples of coal. These samples were taken in the mines by Geological Survey personnel following recommended U. S. Bureau of Mines methods of sampling, which provide for exclusion of mineral bands over -inch in thickness (holmes, The ex cluded bands may be composed of pyrite or pyrite and other minerals. In some in stances, those bands may represent a significant amount of sulfur in comparison to the total sulfur in the resulting face-channel sample.

Book excerpt: Excerpt from Sulfur Reduction of Illinois Coals: Washability Studies; Part 2 Part 1 of this study indicated that the washability characteristics of Illinois coals crushed to a maximum size of 1 inches usually did not vary significantly from the washability characteristics of the same coals when crushed to a maximum size of inch. Because the results with the two size ranges were similar and since the -inch maximum size would allow the use of a smaller quantity of coal for the washability tests, a -inch maximum size was used for all tests described in this report. The minimum size of 28 mesh (tyler screen series) was selected because (1) it was considered the finest size of Illinois coal that could be readily separated by gravity methods, and (2) only a small proportion of the coal would be finer than 28 mesh after crushing and screening in stages to the maximum size of inch. During Part 1 of the investigation, a l-ton sample of raw coal, which generally was sampled in 20 to 30 increments through most of one shift of Oper ation, was obtained from the tipple; a few samples were obtained from the pit. None of the samples was considered representative of a mine's output. A differ ent method of sampling was used for the study described in this report. Instead of obtaining a l-ton sample, an approximately 80-pound sample, which will be referred to subsequently as a column sample, was cut from each of three freshly exposed coal faces at separate working areas of a mine. This procedure pro Vided a total sample of about 240 pounds per mine. Although these samples may not be representative of the output of the mine either, they are considered to be superior to those obtained by the tipple or pit-sampling procedure used in Part 1 of this study. Pace - channel samples, from which mineral bands of more than inch in thickness were excluded in accordance with U. S. Bureau of Mines procedures (holmes, also were cut from the same general locations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Sulfur Reduction of Illinois Coals, Vol. 1: Washability Studies The potential reduction in sulfur (and ash) that can be obtained with a coal can be determined by making float - and sink (washability) tests with the coal in a laboratory. As described in more detail later in this report, this process is essentially one of determining the weight percentages and chemical compositions of the material that is collected from liquid baths of different specific gravities The percentage of coal that floats is commonly called recovery, and the mater ial that sinks is often called reject. A commercial preparation plant cannot provide as precise a separation of float - and sink products as that obtained in the laboratory.

This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of elements (C, N, O, S, Na, Mg, Al, Si, Ca, and Fe) has been determined by point-to-point microanalysis of several maceral components of three samples of Illinois coal. The point-to-point variations for C, Si, Fe, and pyritic S were much greater in the exinites than in the vitrinites. The carbon content of exinites ranged from 40 to 70 weight percent and averaged 52 to 57%. The carbon content of vitrinites was higher, averaging 68 to 82%. The organic sulfur content of vitrinites was nearly the same as that of exinites, but the pyritic sulfur was much higher in the exinites. Both iron and silicon were higher in exinites than in vitrinites. In vitrinites, silicon ranged from 0.01 to 0.30% while iron was generally less than 0.1%. Nitrogen, sodium, and magnesium contents of these coals were near the limit of detectability, and no significant variations were noted. The organic sulfur content of the No. 5 coal and one of the No. 6 coals was in the range of 0.2 to 0.6%, while the other No. 6 coal had organic sulfur above 1% and total sulfur of 3.84%. The organic sulfur was easily distinguished from the pyritic or sulphatic sulfur forms by the local iron content and the variation in the sample current. The solvent-reacted samples showed only small changes in average composition. The differential thermal analysis curves for all three of the coals are remarkably alike, from room temperature to 850/sup 0/C. The microanalyzed residues showed large reductions of organic sulfur content but only small changes in carbon content after heating. Coal samples heated in a microwave oven to 200/sup 0/C for up to thirty minutes did not show significant changes in composition. 6 references, 4 figures, 5 tables.
