What is synthetic petrol? Name the two methods used to convert coal to gasoline.
Answer
Synthetic petrol is a liquid hydrocarbon fuel synthesized from solid coal or gaseous fuels. The two methods are Bergius process and Fischer-Tropsch process.
Synthetic petrol is an artificial liquid fuel resembling natural petroleum, created by hydrogenating solid sources like coal or by synthesizing from carbon monoxide and hydrogen gases (syngas).
Methods to convert coal to gasoline: 1. Bergius Process (Direct method): Direct hydrogenation of powdered coal under high temperature and pressure with a catalyst. 2. Fischer-Tropsch Process (Indirect method): Conversion of coal into syngas (), followed by catalytic synthesis of liquid hydrocarbons.
