Rather than dissolving coal directly into a liquid as in the Bergius process, the FischerTropsch method first transformed coal into a gas, then chemically rearranged the gaseous molecules into liquid fuels and chemicals. The second plant at Louisiana, MO, was completed in 1950 and began full operation in 1951.
