| Abstract |
The report details experimentation on the application of chemical cleaning (desulfurization) technology to a variety of U.S. coals. Run-of-mine coal samples were collected from 35 U.S. coal mines in 13 states. Each sample was treated separately by the Meyers process for selective chemical removal of coal-pyrite and by float-sink procedures for physical coal cleaning. Raw and chemically treated coals were examined for sulfur distribution as well as for selective trace element distribution and other process characterizing features, such as heat content and ash changes and leaching agent residuals. Comparisons of physical and chemical impacts on sulfur reductions are discussed. |
