and power generation; and (b) brown coal (subbituminous and lignite), which is used mostly as onsite fuel. Coal has a wide range of moisture (240%), sulfur (%), and ash content (540%). These can affect the value of the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat ...

4A3. Brown Coal Liquefaction Technology (BCL) Technology overview 1. Background and process overview˜ Economically recoverable coal reserves are expected to total about one trillion tons, about onehalf of which are comprised of lowrank coal such as subbituminous coal and brown coal. Coal has a larger ratio of reserves to production (R/P) than that of oil and natural gas. For the effective ...
· The cleaning of coal by electrostatic beneficiation is based on tribocharging characteristics of pulverized coal particles with diameter smaller than 120 μm. The tribocharging process should be such that the organic coal particles must charge with a polarity opposite to that of the sulfur and the mineral containing particles so that coal can be separated from minerals by using a charge separator.
