Excerpt from Coking of Illinois Coals In its endeavor to promote a more efficient use of coal the Bureau of Mines, in cooperation with the Illinois State geological survey and the University of Illinois, has undertaken an investigation of the coking of Illinois coals The investigation was started by collecting from various sources the data regarding experiments already made by others; these data have been compiled and are presented herein.

Excerpt from Stockpiling Illinois Coal for Coke A critical study of the weathering tests made it apparent that the production of unsatisfactory coke was related closely to reduction in fluidity of the coal blend being coked. It occurred to us that if Illinois coal were to be blended with coals of higher fluidity than the Pocahontas. No. 3, the blend might retain sufficient fluidity to produce good coke even after the Illinois coal had started to weather.

Excerpt from A Survey of the Coking Properties of Illinois Coals Illinois coals from all the mining areas and all the commercially mined seams in the state have been evaluated for their ability to produce both chemical and metallurgical coke. They have been coked both by themselves and in blends, and it has been found that many of these coals that are not suitable for metallurgical coke because of their ash and sulfur content might be used to produce chemical coke where these impurities are not too critical.

Excerpt from Carbonization of Illinois Coals in Inclined Gas Retorts The yield of coke from mixtures was larger than from Illi nois coal alone, and increased as the percentage of Kentucky coal was increased.

Excerpt from Coking Coals of Illinois: Their Use in Blends for Metallurgical Coke Much of the research behind the development of the coal blend at Granite City, and of other blends utilizing Illinois coals, has been carried out in the lab oratories and pilot coke ovens at the Illinois State Geological Survey. The orig inal slot-type oven (reed, 1947) and the newer movable-wall oven (jackman, l955a) have been developed and operated so that coking results closely duplicate those obtained in commercial oven practice. Results of tests made with the pilot oven may be used, therefore, as a dependable guide to anticipate performance of an experimental coal blend in commercial ovens. We wish to thank the coke and steel companies that have furnished us with coals for these tests, and Illinois coal producers who furnished the No. 5 and No. 6 seam coals. We are grateful also to those of our own staff who have co operated in obtaining samples, operating the pilot oven, and making analyses of all coals and cokes.

Excerpt from Coke From Medium-Volatile and Illinois Coals Illinois coals have been used continuously in blends for metallurgical coke since the days of World War II. Their use has presented certain problems in blend ing procedure which have been studied both experimentally and on a commercial scale. Where proper procedures have been developed and followed, the use of Illi nois coal has been found advantageous, involving no sacrifice in coke quality and reducing over-all costs.

Excerpt from Weathering of Illinois Coals During Storage From these tests we conclude that double-screened coal from No. 5 and No. 6 seams in southern Illinois, in the sizes being supplied to metallurgical coke plants, can be stocked safely in contact with air, and without packing, during the six-months winter period at temperatures prevailing in the Chicago and central Illinois district. In summer appreciable oxidation occurs during storage, although to a greater extent with No. 6 coal than with No. 5. It appears, however, that for best coking results none of these coals should be stocked in the usual storage piles in warm weather longer than 30 days.
