The FischerTropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the formation of ...

Without carbon capture technology, coaltoliquid fuel produces twice the emissions as gasoline from conventional crude oil: about 50 pounds of CO2 for liquid coal compared with 27 pounds for conventional gasoline. Coaltoliquid is also a waterintensive process, using about ten gallons of water for every gallon of fuel produced.

For example, it is possible to produce synthetic jet fuel, diesel, or gasoline for conventional planes, ships, trucks, and cars. The main difference between fossil and synthetic fuels is how they are produced: fossil fuels are formed over millions of years underground from organic matter that is turned into coal, natural gas, or oil.

Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...

Abstract. To produce liquid fuels from coal, either direct or indirect liquefaction routes can be used. The discussion of the former route is the subject of Chapter 6; the latter route will be discussed here. The indirect liquefaction route consists of the conversion of coal to synthesis gas (hydrogen plus carbon monoxide), and then the ...

In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

The beginning of the history of synthetic fuels datesgaso to 1913 when the first process of direct coal liquefaction (DLC) by mean of hydrogenation was patented in Germany by the chemist Friedrich Karl Rudolf Bergius () The basic principle of DLC was the use of coal instead of petroleum/crude oil to obtain liquid hydrocarbons used for fuel or as a base for producing other chemicals.
