Refined coal Wikipedia

Refined coal Wikipedia

Refined coal is the product of the coalupgrading technology that removes moisture and certain pollutants from lowerrank coals such as subbituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically precombustion treatments and processes that alter the characteristics of coal before it is burned.
