What is the Best Coal for Coke Making

2021-4-6  The average 2-inch shatter index of furnace-cokes made from coals of the Appalachian field is approximately 60 percent. Perrott and Kinney found an average of 67 percent for cokes used at eight furnaces in Alabama and Pennsylvania; the high figure was 70 and the low 64 percent. Some of these cokes were made in byproduct and some in beehive ovens.
