Excerpt from Contributions to the Study of Coal: Influence of Structural Irregularities Upon the Chemical Character of No. 6 Coal in Franklin and Williamson Counties, Illinois; Distribution of Sulfur in Illinois Coals and Its Geological Implications Within the large area of the Illinois coal basin, the rank of coals varies through almost the entire range of the high-volatile group, in general increasing southward or southeastward across the basin. The rate of variation within the greater part of the area is so gradual that the chemical character of any bed is well represented by average values for fairly large areas, such, for example, as are represented by individual counties. This is particularly true of the calorific value for the dry, mineral matter-free coal - what has been designated the unit coal calorific value. County average unit coal values have for several years been recommended by the State Geological Survey as generally applicable to the coal in individual mines in any county. It has been known for some time, however, that the rate of varia tion in rank is considerably more rapid across the counties lying along the southern margin of the coal basin than across the counties to the north, so that in Franklin, Williamson, Jackson, Saline and Gallatin counties, analyses of individual samples are likely to vary more from county averages than is the case north of the border belt. Inasmuch as structural conditions affecting the coal beds are more irregular in this marginal belt than elsewhere in the State it has been suspected that variations in the chemical character of the coal, indicative of varia tions in rank, would eventually, with the accumulation of sufficient analytical and structural data, be found definitely related to structural irregularities. It was also realized that the discovery of such relation ships would probably necessitate the eventual abandonment oi county average values as the basis for standardization and the adoption cf values based upon the character of the coal bed within more natural structural units.

Excerpt from Specific Gravity Studies of Illinois Coal The Object of this bulletin is to present the results of a study of (1) the effect of moisture upon the specific gravity of coal, and (2) the methods of determining the specific gravity of coal. The commercial aspects of the problem are discussed, and values are given for the specific gravity of coal from many of the mining districts of the State of Illinois. The specific gravity of bright and dull coal is also considered. The investigation was carried on under the direction of Professor H. H. Stock of the University of Illinois, who suggested the problem and whose advice and criticism were of great value. Experiments were conducted in the laboratories of the Department of Mining Engineering of the University of Illinois, and field trips were made to the Vermilion county coal field, where samples of coal were collected from a number of mines. Other samples were obtained from various sources. The author is indebted to Professor E. A. Holbrook of the Department of Mining Engineering of the University of Illinois for assistance in securing sam ples of coal and for valuable suggestions and criticisms during the prog ress of the work; and also to Professor S. W. Parr of the Department of Chemistry of the University of Illinois, and Mr. Fred H. Kay, of the Illinois State Geological Survey, for advice.

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.

Excerpt from Chemistry, Uses, and Limitations of Coal Analyses: Report of Investigations No. 220 A number of the conclusions are those I have formulated during many years of coal analysis work. I owe much to my associates, past and present at the Illinois State Geological Survey and to coal analysts and technologists in the United States and in several foreign countries with whom I have dis cussed numerous problems relative to this type of analysis. I hope that the report will be helpful to coai' analysts and technologists. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Internal Surface Area, Moisture Content, and Porosity of Illinois Coals: Variations With Coal Rank The surface area of a solid is an important physical parameter, which can generally be correlated with the solid's rate of reactivity. In general, the greater the surface area, the higher the rate of reactivity in such processes as solubilization, catalysis, ion exchange, thermal decomposition, and corrosion; for coals, combustion and weathering also can be included.
