Consider the following pairs:

  1. Bergius process→ Hydrogenation of coal to produce liquid hydrocarbon
  2. Karrick process→ Low-temperature carbonization of coal
  3. Fischer–Tropsch process→ Converts a mixture of carbon dioxide and hydrogen into liquid hydrocarbons

   Which of the above is/are correct?

Answer: [D] 1, 2 & 3

Fischer-Tropsch process converts a mixture of carbon monoxide and hydrogen into liquid hydrocarbon. The Bergius process is a method of production of liquid hydrocarbons by hydrogenation of high-volatile bituminous coal at high temperatures and pressure. The Karrick process is related to low temperature coal carbonization. It could be used to distil out synthetic fuels-unconventional oil and syngas.
