Abstract

Coal cleaning technology is reported for fuel use and advanced use of coal. Coal cleaning technologies are selected through literature survey, and evaluation of performance of desulfurization/deashing are made through laboratory-scale experiments. As coal cleaning technology for fuel use, selected are fine particle dense media cyclone, column flotation, improved OA process (oil agglomeration), magnetic separation, and microbiological treatment. As coal cleaning technology for advanced coal use, alkali leaching and selected agglomeration. Results of the laboratory experiments indicate that the improved OA process and alkali leaching are comparatively applicable to any kind of coal, while fine particle dense media cyclone and magnetic separation are largely dependent on coal kind. Moreover, mineral composition to be removed is different by cleaning technology. In magnetic separation, for example, Fe, Ca, etc. decrease selectively, which shows that slugging at combustion is expected to be reduced. On the other hand, further study is needed for slurry fuel of clean coal and application to high added value fields. 80 refs., 180 figs., 78 tabs.
