Coal to chemical production is in China where coal dependent provinces such as Shanxi are struggling to control its pollution. Refined coal is the product of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals. It is one form of several precombustion treatments and processes for coal that alter coal's characteristics before it is burned. Thermal efficiency improvements are achievable by improved pre-drying (especially relevant with high-moisture fuel such as lignite or biomass).The goals of precombustion coal technologies are to increase efficiency and reduce emissions when the coal is burned.

The phrase "what cheer with you" is an ancient English greeting dating back at least to the 15th century.
