释义
Fischer–Tropsch process

Chemistry
  • An industrial method of making hydrocarbon fuels from carbon monoxide and hydrogen. The process was invented in 1925 and used by Germany in World War II to produce motor fuel. Hydrogen and carbon monoxide are mixed in the ratio 2:1 (water gas was used with added hydrogen) 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. The gasoline fraction contains a high proportion of straight-chain hydrocarbons and has to be reformed for use in motor fuel. Alcohols, aldehydes, and ketones are also present. The process is also used in the manufacture of SNG from coal. It is named after the German chemist Franz Fischer (1877–1947) and the Czech Hans Tropsch (1889–1935).


Chemical Engineering
  • A process used for producing hydrocarbons from carbon monoxide and hydrogen. Named after German chemist Franz Fischer (1852–1932) and Czech Hans Tropsch (1839–1935), the process was invented to produce motor fuel in Germany during the Second World War. The process involves passing the reactants over a nickel or cobalt catalyst at 200°C. The general reaction is:

    nCO+(2n+1)H2CnH2n+2+nH2O

    The resulting complex mixture of hydrocarbons is then separated into various fractions. The process also results in the formation of alcohols, aldehydes, and ketones.
