Explain fermentation of coal..
Answers
Answer:
Explanation:
->Fermentation of coal is conducted to produce biogas.
-> Microbes utilized in the study were isolated from gassy coal mine water.
->Coal used in this study was hard coal of Jitpur coal mine.
-> Above 90% methane found in biogas at optimum condition.
-> Microbes found to be site specific or habituate on coal of same mine.
Answer:
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, CO2, and H2 in synthesis gas. Early studies with C. ljungdahlii showed that relatively high concentrations of ethanol were produced. This process involves three main steps:
1. Gasification: Thermal gasification at temperatures of up to 2,200°F in a reducing, very low oxygen atmosphere transforms organic materials into simple CO, CO2 and H2 gases.
2. Fermentation: The acetogenic C. ljungdahlii convert the carbon monoxide into ethanol.
3. Distillation: Ethanol is separated from hydrogen and water.
