U.S. coal imports. Although the United States produces a large amount of coal—about 756 million short tons (MMst) in 2018—some coal-burning power plants along the Gulf Coast and the Atlantic Ocean sometimes find it cheaper to import coal from other countries than to obtain coal from U.S. coal-producing regions.

Thousands of products are made with coal or coal by-products, including aspirins, soap, dyes, solvents, plastics, and fibers such as rayon or nylon. Coal is an important ingredient in production of products that require activated carbon, carbon fiber or silicon metal.
Shenfu bituminous coal (SFBC), Geting coal (GTC), Shengli lignite (SLL), and Holingola coal (HLGLC) were oxidized by UV light radiation with aqueous H2O2 over SFC/TiO2 in a closed suspension system (CSS) to understand structural characteristics of 4 typical Chinese coals. Raw and oxidized coals were dried and extracted with acetone thoroughly to ensure residue extraction.

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
Coal Severance Tax. Coal Conversion Facilities. The coal conversion facilities privilege tax is imposed on electrical generating plants that have at least one generating unit with a capacity of 10,000 kilowatts or more, other coal conversion facilities that consume 500,000 tons or more of coal per year, and coal beneficiation plants.

Direct conversion refers to processes in which coal or biomass feedstocks are converted directly into intermediate or final products, avoiding the conversion to syngas via gasification. Direct conversion processes can be broadly broken up into two different methods: Pyrolysis and carbonization, and hydrogenation. [citation needed]
Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals.This process is often known as "Coal to X", where X can be many different hydrocarbon-based products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).
In complex substances such as are found in coal wastes and coal-conversion products, neutron activation analysis (NAA) is the method of choice for many trace element analyses because of its relative freedom from matrix effects. The NAA method can be divided into Instrumental NAA (INAA), and Radiochemical NAA (RNAA).
Two-stage DCL process was developed in recognizing that the conversion process probably proceeds in two steps – first, coal dissolution, in which the coal is converted to a soluble form with high molecular weight but with little change in the average composition from the original coal; and a second stage in which the dissolved products are ...

Measuring energy in food. Food calories are a measure of energy in food. One food calorie is equal to 1,000 calories, or 1 kilocalorie. For example, the energy in a 300-food calorie ice cream cone is about the same as the amount of electricity required to light a 100-watt incandescent light bulb for 3.5 hours.
Coal is best known for its role supplying electricity throughout the United States—nearly half of the country's electricity comes from coal. But while the vast majority of it is burned at conventional coal-fired power plants, coal is also turned into a gas for conversion into electricity, hydrogen, and other energy products.
• Coal Conversion answers energy security concerns, logistics issues and search for better coal monetization. • Environment is a key issue. Solutions exist: technological improvements, CCS and combination with biomass. • Processes are operated commercially. • Conversion is competitive at current energy prices, although capital intensive.
History. In the past, coal was converted to make coal gas, which was piped to customers to burn for illumination, heating, and cooking. High prices of oil and natural gas are leading to increased interest in "BTU Conversion" technologies such as gasification, methanation and liquefaction. The Synthetic Fuels Corporation was a U.S. government-funded corporation established in 1980 to create a ...
