अवलोकन

Fischer-Tropsch (FT) synthesis converts synthesis gas (CO + H₂) into liquid hydrocarbons, producing synthetic fuels and waxes from coal, natural gas, or biomass. Developed in Germany in the 1920s, the technology was used extensively during WWII and in apartheid-era South Africa (Sasol). Today, Shell's Pearl GTL plant in Qatar is the world's largest, converting natural gas to 140,000 barrels/day of clean diesel and base oils. FT fuels are sulfur-free and have excellent combustion properties.

रासायनिक प्रक्रिया

Syngas (H₂:CO ratio of 2:1) is passed over iron or cobalt catalysts at 200-350 degrees C and 10-40 bar. The Anderson-Schulz-Flory distribution governs the product slate, which ranges from methane to heavy waxes (C₁-C₁₀₀+). Cobalt catalysts favor long-chain paraffins, while iron catalysts produce more olefins and oxygenates.

nCO + (2n+1)H₂ →[Co or Fe catalyst] CₙH₂ₙ₊₂ + nH₂O (paraffins)
nCO + 2nH₂ → CₙH₂ₙ + nH₂O (olefins)

Environmental Impact

Coal-based FT synthesis (CTL) has very high CO₂ emissions — approximately double that of conventional petroleum. Gas-based FT (GTL) has lower emissions. Biomass-based FT (BTL) can be near carbon-neutral. All FT fuels burn cleaner than petroleum-derived fuels due to zero sulfur content.
