1933 and used by Germany in World War II to produce
motor fuel. It was Named after the German chemist Franz Fischer (1852-1932)
and the Czech Hans Tropsch (1839-1935).
An industrial method of making hydrocarbon
fuels from carbon monoxide and hydrogen. Hydrogen
and carbon monoxide are mixed in the ratio 21 and
passed at 200 °C over a nickel or cobalt catalyst.
The resulting hydrocarbon mixture can be separated
into a higher-boiling-fraction for diesel engines
and a lower-boiling gasoline fraction.
fraction contains a high proportion of straight-chain
hydrocarbons and has to be reformed for use in motor
The process is also used in the manufacture
of SNG from coal.
