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 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 ...
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.
The coal liquefaction process includes the production of synthesis gas from coal and the subsequent conversion of synthesis gas into liquid fuels (gasoline, diesel, jet fuel). Several wellestablished technologies are known both for coal gasification and fuel synthesis. At the beginning of this decade, a novel process was developed for 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".
They have developed a direct FischerTropsch process that produces synthetic petrol, diesel, or kerosene straight from the reactor with no need for cracking and only minimal refining. 'Our process avoids making very heavy molecules in the first place, and aims to make products that are already in the right specification,' explains Shah.
The economic viability of producing synthetic natural gas (SNG) through coal gasification is heavily dependent on the market prices of natural gas and the coal feedstock to be used, in addition to the capital cost of the gasification plant.
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 ...
