Thermal upgrading is a promising way to use lignite efficiently and safely. However moisture readsorption properties of the upgraded lignite would partially offset the upgrading effect. Asphalt is so repellent that it could be used as an additive in lignite thermal upgrading to prevent moisture readsorption of upgraded lignite. In this study a Chinese lignite upgraded at various temperatures
Get PriceWhat are the types of coal USGS
Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants bituminous coal subbituminous coal or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam which drives a turbine which produces electricity. In 2019 about 23 percent of
