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).
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.
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.

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.

Advanced combined-cycle and fuel cell power generation technologies will also require the conversion of coal to clean gaseous fuels. In addition to the above major uses, economical use of clean gaseous and liquid products from coal can provide a source of feedstock for chemicals production.
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.
Oct 31, 2018· Beneficial Use of CO 2 from Coal-Fired Power Plants for Production of Animal Feeds – MicroBio Engineering (San Luis Obispo, CA) intends to develop a process to produce microalgal biomass for the conversion of CO 2 from coal-fired power plant flue gas into animal feeds, to demonstrate the potential of power plant CO 2 utilization for ...
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 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.

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 utilization, combustion of coal or its conversion into useful solid, gaseous, and liquid products. By far the most important use of coal is in combustion, mainly to provide heat to the boilers of electric power plants. Metallurgical coke is the major product of coal conversion.
The Proximate Analysis of any coal i.e. the % content of Moisture, Ash (A), Volatile Matter (VM), Fixed Carbon (FC)– also Sulphur (S)and Calorific Value (CV)– can be expressed on any of the above bases. Coal Conversion Facts

Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities.

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).
