The Fischer-Tropsch technique is designed to achieve the ______________________?
Show answer Hide answer
Answer: B. Synthesis of gasoline (from water gas)
Explanation
The Fischer-Tropsch process catalytically converts carbon monoxide and hydrogen into liquid hydrocarbons. Water gas provides the exact mixture of carbon monoxide and hydrogen required for the reaction. Advanced catalytic synthesis transforms gaseous reactants into synthetic gasoline and diesel. German chemists Franz Fischer and Hans Tropsch developed the catalytic synthesis in the 1920s. Cobalt or iron catalysts facilitate the chain-growth polymerization of hydrocarbon molecules. Water gas is generated by passing steam over hot coke or coal beds.
This technology enables countries without crude oil reserves to produce liquid fuels from coal. Synthetic fuel plants use this method to secure domestic liquid hydrocarbon supplies. Modern variations also utilize natural gas or biomass as primary synthesis feedstocks. Gasification of coal produces water gas but is a separate preparatory step. Direct hydrogenation of coal to produce gasoline involves different chemical reactor mechanisms. Stating none of these is incorrect because synthetic gasoline production is the correct answer.
