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 FisherTropsch process for converting coal into the liquid fuels of gasoline and diesel.
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.
The conversion of most types of coal (with the exception of anthracite) primarily to petroleumlike hydrocarbon liquids which can be substituted for the standard liquid or solid fuels used to meet transportation, residential, commercial, and industrial fuel requirements.
This paper overviews the recent advances in the research on direct coal liquefaction technology with respect to the influencing factors (temperature, solvent, pressure, atmospheres, etc.) for DCL reactions, the effects of coal pretreatments (swelling, thermal treatment, hydrothermal treatment, etc ...

As the cost of production is a key determinant of longterm viability, developing methods that reduce the cost of direct coal liquefaction has posed a challenge .
The major objective of coal liquefaction is to produce synthetic oil to supplement the natural sources of petroleum. Liquid and solid products from coal can be used for fueling transportation vehicles, providing fuels for power generation, and yielding raw materials for chemicals.
Wave Liquefaction™: New Markets for Coal A novel REMS approach to manufacturing fuels, chemicals, and materials from coal, natural gas, and other feedstocks.
The acute toxicity of a series of potential streams from the EDS coal liquefaction process have been assessed in animal bioassays. In general, the materials present minimal acute toxic hazards.
A coal liquefaction facility needs only coal and water to produce plastic, rocket fuel and lubricant. It uses 10 coal and 50 steam plus 25 heavy oil as a catalyst to produce 10 more heavy oil, 15 light oil and 20 petroleum gas.
"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.
Furthermore, the developed materials and new processes are ... "Development of Coal Liquefaction Technology A Bridge for Commercialization," Nippon Coal Oil Co., Ltd. 3) Haruhiko Yoshida: "Coal Liquefaction Pilot Plant," New Energy and Industrial Technology Development Organization.
Abstract 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.
The syntheis and characterization of two series of supported metal compounds has been achieved during the initial period of grant support. These potentially catalytic materials were prepared from ...
9 天前· A new project called "Coal: PostFuel" by Jesper Eriksson explores a "speculative material future" for the stuff. Considering the role it plays in Britain's history, could it — and should it even be allowed to — develop a sort of nostalgia around it .

Aug 24, 1995· Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and conversion industry is commonly referred to as "coal conversion" or "Coal To X". "Coal to Liquid Fuels" is commonly called "CTL" or "coal liquefaction", although "liquefaction" is generally used for a nonchemical process of becoming liquid.
This is the first time that the coal direct liquefaction residue modified asphalt was used in high temperature and rainy regions in the southern China and its highways, suggesting that the coal direct liquefaction residue modified asphalt work has taken a new step.
