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 ...

the FischerTropsch synthetic fuel industry. Andy Extance discovers how it is now adapting to polish its reputation In short The FischerTropsch process was developed to turn plentiful coal into oil and liquid fuels when supplies were restricted The catalytic process turns syngas (CO and H2) into longer chain hydrocarbon fuels

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.

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 problem of producing synthetic liquid fuels by alternative routes is addressed. Industrial processes known as gas to liquid (GTL) and coal to liquid (CTL) are considered and compared to a hybrid process presently developed, which combines features of both GTL and CTL.. Detailed process models are developed.

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. ...
