Using coal, steam, and oxygen, the Fischer-Tropsch Procedure converts coal into a liquid fuel.
Step-by-step explanation;
- The Fischer-Tropsch process is a series of chemical reactions that involve the conversion of hydrogen and carbon monoxide into liquid hydrocarbons by using a catalyst.
- Coal liquefaction is the process by which coal is converted to liquid hydrocarbons. This is done using the Fischer-Tropsch process.
- The process is a key component of gas to liquid technology. It produces synthetic lubrication oil and synthetic fuel including natural gas, biomass or coal.
