new materials for coal liquefaction - agriturismodesole

Coal liquefaction is a process that converts coal from a solid state into liquid fuels, usually to provide substitutes for petroleum products. Coal liquefaction processes were first developed in the early part of the 20th century but later application was hindered by the relatively low price and wide availability of crude oil and natural gas.

New York City (!!!) Improves Coal Liquefaction

29/10/2009  Pretreatment of coal by reaction with subcritical steam enhances its performance in direct liquefaction. Illinois No. 6 coal, first reacted with 51 atm of steam for 15 min at 340 °C, was liquefied in a coal injection autoclave to provide rapid heating. Liquefactions were carried out with raw and pretreated coal at high-severity (400 °C, 30 min) and low-severity (385 °C, 15 min) conditions ...

Liquefaction of Coal - eolss

Coal liquefaction is an industrial process in which coal as raw material, through chemical reactions, is converted into liquid hydrocarbon mixture, which, under further processing, becomes desired liquid fuels or chemical feedstock. Therefore, the main purpose of coal liquefaction lies in production of either synthetic oil as a partial substitute resource for crude oil or aromatic hydrocarbons ...

Reaction Engineering of Direct Coal Liquefaction

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 investigated. Since the US is rich in coal resources, this is one way to be energy independent.
