Ethanol from coal - Wikipedia

Ethanol from coal is the ethanol produced using coal as its carbon source. The anaerobic bacterium Clostridium ljungdahlii produces ethanol and acetic acid from CO, CO 2, and H 2 in synthesis gas.Early studies with C. ljungdahlii showed that relatively high concentrations of ethanol were produced. This process involves three main steps: Gasification: Thermal gasification at temperatures of up ...
