Carbonizing Properties: Tennessee Coals From The Jellico Bed In Campbell County And The Sewanee Bed In Marion County - Introduction And Summary

THIS REPORT gives results of an investigation of the carbonizing properties of two Tennessee coals, one from the Jellico bed in Campbell County and the other from the Sewanee bed in Marion County. Jellico coal and blends with 20 and 30 percent Pocahontas No. 3 coal were carbonized at 800° and 900° C. by the BM-AGA method. Sewanee coal was carbonized by the same method at 800°, 900°, and 1,000° C.; blends with coals of similar and different ranks were carbonized at 800° and 900° C. The coals were subjected to various physical and chemical tests, including complete chemical analyses, low-temperature assays, and agglutinating, free-swelling, friability, plasticity, and expansion tests. The Tennessee coal field is a part of the Appalachian field, which extends from northern Pennsylvania to central Alabama. The Jelico bed, one of the most important in the State, is part of the Jellico formation, which is above the Lee formation of the Lower Pottsville. Sewanee coal bed belongs to the Sewanee conglomerate and is stratigraphically lower than the Jellico bed.
