Abstract The report given detailed experimental results of applying chemical desulfurization technology to a variety of U.S. coals. Run-of-mine coal samples were collected from 15 U.S. coal mines in 11 states. Each coal was treated separately by the Meyers Process (ferric sulfate extraction) and float-sink fractionation (physical coal cleaning). The Meyers Process removed 83-99% of the pyritic sulfur (40-64% of the total sulfur) from all the coals that contained sufficient pyritic sulfur for accurate sulfur determination. The Meyers Process also removed significant amounts of selected trace elements along with the pyrite. Solvent extraction of organic sulfur was investigated. (Modified author abstract)
