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 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 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 Illinois Coals, an Experimental Slot-Type Oven Midwestern by-product coke ovens require annually millions of tons of high volatile bituminous coals Which are shipped from the Appalachian coal fields in West Virginia, Pennsylvania, and eastern Kentucky. Illinois has larger reserves of high-volatile bituminous coals than any other state east of the Rockies. Though the Appalachian coals are principally of higher rank than the midwestern, the reserves of these high-rank coals are being depleted rapidly. Because of this and the present critical transportation problem, the Illinois State Geological Survey, aided by the Office of Production Research and Development, War Production Board, initiated a research program to study the problem of substituting mid western coals for a portion of the eastern high-volatile coals now being carbonized in midwestern coke ovens. Previous commercial and semicommercial experience has shown that metallurgical coke can be made from certain Illinois coals. The research program includes the design, construction, and operation Of a pilot-size coke oven to duplicate carbonizing conditions in commercial slot-type ovens. A slot-type pilot-size coke oven of soo-pound coal capacity, electrically heated to ensure accurate temperature control, is described. The yields and properties of the coke and by-products recovered from this small experimental oven correlate closely With those obtained by carbonizing the same coals in commercial ovens. Thus this Oven is a reliable guide for commercial operations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
