Reaction Engineering of Direct Coal Liquefaction

Robinson, Ken K. - In: Energies 2 (2009) 4, pp. 976-1006

Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to produce synthetic fuels when there was no oil allowed into the country. Since then, it has been studied in the United States and many different technologies have been...
