The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts , typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres.
The water–gas shift reaction (WGSR) describes the reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen: CO + H 2 O ⇌ CO 2 + H 2. The water gas shift reaction was discovered by Italian physicist Felice Fontana in 1780. It was not until much later that the industrial value of this reaction was realized.
Indirect Fischer–Tropsch ("FT") technologies were brought to the United States after World War II, and a 7,000 barrels per day (1,100 m 3 /d) plant was designed by HRI and built in Brownsville, Texas. The plant represented the first commercial use of high-temperature Fischer–Tropsch conversion.
Gas to liquids (GTL) is a refinery process to convert natural gas or other gaseous hydrocarbons into longer-chain hydrocarbons, such as gasoline or diesel fuel. Methane -rich gases are converted into liquid synthetic fuels. Two general strategies exist: (i) direct partial combustion of methane to methanol and (ii) Fischer–Tropsch -like ...
Catalytic fast pyrolysis. Catalytic fast pyrolysis is a fast process in which the cellulose is broken down to a liquid biofuel. In this approach the cellulose is heated to 500 degrees Celsius in less than one second in a chamber to break apart the molecules. The catalyst forms chemical reactions that remove oxygen bonds and form carbon rings.

Fischer–Tropsch is the oldest of the ICL processes. In methanol synthesis processes syngas is converted to methanol , which is subsequently polymerized into alkanes over a zeolite catalyst. This process, under the moniker MTG (MTG for "Methanol To Gasoline"), was developed by Mobil in the early 1970s, and is being tested at a demonstration ...
From 1917 to 1920, Tropsch worked in a tar distillery of the Rütgers company in Niederau, but returned to the Kaiser Wilhelm Institute for Coal Research in 1920, staying until 1928. There he worked with both Franz Fischer and Otto Roelen. It was during this time that the ground-breaking inventions of the Fischer–Tropsch process were patented.
