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 ...
800 million tons of coal since 1955. continues to supply about 29% of South Africa's fuel needs from While the technology for producing synthetic fuels from coal or natural gas has been around for decades, it was not profitable when oil prices were below 30 per barrel. The Department of Energy estimates that the first coal to fuel ...
The utility of syngas as a fuel was realized in Germany during World War II, when gasoline shortages affected transportation for both the military and civilians. At the time, it was known that coal could be converted to liquid hydrocarbons through either the Bergius process, developed by German chemist Friedrich Bergius, or the FischerTropsch ...

SYNTHETIC FUELSSynthetic fuels are usually thought of as liquid fuel substitutes for gasoline and diesel fuel made from petroleum sources. In broad context, the source of these synthetics can be any feedstock containing the combustible elements carbon or hydrogen. These include coal, oil shale, peat, biomass, tar sands, and natural gas. Source for information on Synthetic Fuels: Macmillan ...
Both the FischerTropsch and MTG processes convert coal into synthesis gas before converting it to the final liquid products. However, their respective product slates are very different.
Synthetic Fuel Technology Synthetic fuels can be traced to the mid19 th century processes of making coal oil, coal gas, and the later manufacture of town gas. Coal oil was introduced as a substitute for more costly illuminating fuels, particularly premium whale oil. Originally sold under the trad e name of kerosene, coal o il was in turn ...
The hybrid process couples features of both CTL and GTL, to decrease the amount of CO 2 emitted per kilogram of liquid fuel produced. In fact, part of the carbon dioxide produced by coal gasification and water gasshift reaction can be converted into syngas by dry reforming using methane.
Synthetic natural gas production process overview. In Section 3 of the paper, researchers presented various processes used to generate SNG through renewable and nonrenewable methods. Where nonrenewable methods use coal, and renewable methods use biomass in the form of wood, agricultural waste, manure, amongst others.
By John Sullivan, Office of Engineering Communications on Nov. 27, 2012, 9 The United States could eliminate the need for crude oil by using a combination of coal, natural gas and nonfood crops to make synthetic fuel, a team of Princeton researchers has found. Besides economic and national security benefits, the plan has potential ...
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.
coal resources: it contains 25% of the world's coal reserves, and the energy content of those reserves exceeds the energy content of the world's known recoverable oil (DOE 2008). Still, increasing consumption—and the resultant increasing price—of natural gas are
Much attention has been focused on reducing the use of petroleum products as fuels, so synthetic gas (Syngas) introduces a great opportunity for energy sustainable developments. Syngas is created either by gasification of plants biomass or waste products (carbonbased) pyrolysis. In principle, Syngas can be produced from any hydrocarbon feedstock. It mainly affects the combustion process in ...
Technology has come a long way since the first coalderived liquid fuel (a synthetic crude oil) was produced through direct liquefaction in the early 1900s. In 1925, Franz Fischer and Hans Tropsch used an indirect liquefaction process, which still bears their name, to produce excellent transportation fuels. Germany had 25 liquefaction plants ...
For the specific process used in most synthetic gas production, the efficiency is somewhere around 5060%. ... For example the FischerTropsch process, which is used to make gasoline out of coal. If we take slightly different fuels into account, like Biodiesel, there are many more methods to make synthetic fuels. ...

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 FischerTropsch process and a fourth method, the hydrogenation process, changed coal directly into gasoline. As coal is a hydrocarbon containing little hydrogen and gasoline is a hydrocarbon with a high hydrogen content, the problem consisted of attaching hydrogen molecules to coal, thereby liquefying it. ... At the peak of their synthetic ...
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 ...

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 ...
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 ...
