How can coal be converted to petrol?
Dermot - Well the South Africans have been doing this for a very long time because of the years of sanctions. The well-known technology is called Fisher-Tropsch technology and that can be used to synthesise hydrocarbon chains. Traditionally, the process was used for synthesising diesel but you can synthesise a naptha-type material if you want to or a kerosene type material. It’s just a question of optimising the reaction conditions and choosing the right catalyst. People are starting to develop a range of fuels now from synthesis gas.
Jeremiah asked the Naked Scientists: Hi guys, how can coal be converted to petrol? What do you think? Jerryade, Sat, 6th Sep 2008
Motor fuel has been obtained from coal tar...
You can make something like petrol from so called "synthesis gas"
i saw in a book that you can convert it by spraying a paste of coaldust and oil containng iron oxide and alkali as catalyst into hydrogen at 200 atm pressure and 450 degree celsius. The product gotten after are hydrocarbon gases and a liquid oil. On distillation, this oil yields a fraction suitable for petrol. Jerryade, Thu, 11th Sep 2008
