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 led to increased interest in "BTU Conversion" technologies such as gasification, methanation and liquefaction.
Coal liquefaction is a process of ... Indirect liquefaction processes generally involve gasification of coal to a mixture ... 3,960,000 (Nm 3 /d) syngas capacity ...
Known as the Eastman Integrated Coal Gasification facility, it first opened in 1983 and is designed to process syngas from the gasification of Southwest Virginia and Eastern Kentucky coal, using Texaco gasifiers (now GE gasifier technology [15]). The intermediate products of syngas conversion are methanol and CO; these are further converted ...
The underground coal gasification process. Underground coal gasification converts coal to gas while still in the coal seam (in-situ). Gas is produced and extracted through wells drilled into the unmined coal seam. Injection wells are used to supply the oxidants (air, oxygen) and steam to ignite and fuel the underground combustion process ...
It is the largest coal liquefaction plant and the largest single emitter of greenhouse gas in the world. Secunda CTL consists of two production units. The Sasol II unit was constructed in 1980 and the Sasol III unit in 1984. [1] It has total production capacity of 160,000 barrels per day (25,000 m 3 /d). [2]
Complete gasification gas: Gas-evolving coal or other organics. Manufactured by a complex, staged process where as coal travelled down the vertical axis of an upright, semi-cylindrical reaction chamber, it would be subject to different chemical reactions based on what was being fed into that area of the reaction chamber.
The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons. [ 1 ] In the usual implementation, carbon monoxide and hydrogen, the feedstocks for FT, are produced from coal , natural gas , or biomass in a process known as gasification .
Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. Mixing in biomass and using carbon capture and storage (CCS) would emit slightly less than the oil process but at a high cost. [101] State owned China Energy Investment runs a coal liquefaction plant and plans to build 2 more. [102]
