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.

Sustainable fuels, known as synthetic gasoline or efuel, could be the alternative to traditional hydrocarbons in cars with traditional engines. This would be the great news or, rather, the great response that combustion cars could have so as not to disappear. And it is not that it is something new, far from it, since the production system of ...

The Great Plains Synfuels Plant (GPSP) in Beulah, North Dakota has been in operation producing synthetic natural gas (SNG) from lignite coal for 25 years and remains the only coaltoSNG facility in the United States. In addition to the production of SNG, the plant also produces high purity carbon dioxide (CO2), which is distributed through a pipeline to end users in Canada for enhanced oil ...

Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, in various gas often contains some carbon dioxide and is principally used for producing ammonia or is combustible and can be used as a fuel. Historically, it has been used as a replacement for gasoline, when gasoline supply has been limited; for example, wood gas was used to power cars ...

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 ...

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.

A common characteristic of many types of synthetic fuels is that they are the product of an energy carrier molecule reacted with hydrogen. As such, several recent articles have referred to fuels originating from carbon dioxide and hydrogen as synthetic fuels 8, 9. Examples include fuels produced from coalderived syngas or purified biogas (to ...

Synthetic, or carbonneutral, fuels capture CO₂ in the manufacturing process. In this way, this greenhouse gas becomes a raw material, from which gasoline, diesel, and substitute natural gas can be produced with the help of electricity from renewable sources. One further crucial advantage of the combustion engine using synthetic fuels is that ...

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 ...
