Coal liquefaction is a process that has been around for a long time. Although relatively unfamiliar in the American energy vocabulary, it dates back to 1923 when German scientists developed the Fisher-Tropsch process for converting coal into the liquid fuels of gasoline and diesel.
The use of coal as a source of transportation fuel is currently economically unfavorable due to an abundant world petroleum supply and the relatively high cost of coal liquefaction. Consequently, a reduction in the cost of coal liquefaction, for example by using less and/or less costly catalysts or ...

He engaged in the research and development of brown coal liquefaction for 20 years (1976–1998) at Kobe Steel, Co ...
Coal liquefaction has historically been used in countries without a secure supply of petroleum, such as Germany (during World War II) and South Africa (since the early 1970s). The technology used in coal liquefaction is quite old, and was first implemented during the nineteenth century to provide gas for indoor lighting (Speight, 2013a).
Jan 09, 2006· "Methods of coal liquefaction have been available since the beginning of the last century, but the cost has caused us to search for more effective new processes," explains Matthias W. Haenel.
