The FischerTropsch process is a gas to liquid (GTL) polymerization technique that turns a carbon source into hydrocarbons chains through the hydrogenation of carbon monoxide by means of a metal catalyst. The feedstock is typically coal or natural gas, though more exotic (and carbon neutral) possibilities such as removing CO 2 from the ocean or ...

The process was such a success that coalrich Germany used it during World War II to produce a replacement fuel for traditional fossilbased petroleum. In fact, 92% of Germany's air fuel and over 50% of its petroleum supply in the 1940s was created using the coal liquefaction process pioneered by Fischer and Tropsch. A century later, ...
