The method, called the Fischer-Tropsch process, was developed in Germany in the 1920s as a way to convert coal to liquid fuels. The chemistry is complicated, but it basically takes the carbon and hydrogen from the feedstock and reassembles them into the complex chains that make up fuels like gasoline and diesel.

ICL includes two steps; in the first step, coal is converted into syngas ( Coal+H2O-CO+H2), and during the last step, syngas is synthesized in the presence of a catalyst into liquid fuels. Syngas can be converted into liquid hydrocarbon through the Fischer-Tropsch process or by converting syngas into oxygenates such as methanol, …

Liquid Fuel. Most liquid fuels are derived from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust. The fumes of the liquid fuel are flammable instead of the liquid. Advantages: Higher calorific value per unit mass. Burn without ash, clinkers, etc. Controlling the combustion is easier.

Biofuels are renewable. Biofuels are an alternative to fossil fuels. Biofuels reduce greenhouse gas emissions. Fossil fuels produce toxic byproducts that biofuel do not. Biofuel production is less labor-intensive than oil and coal extraction, which reduces the cost of fuel production. The use of biofuels can help mitigate climate change.

Disadvantages. Fossil fuels emit carbon dioxide when burnt which is a major greenhouse gas and the primary source of pollution. This has contributed to global warming. They are a non-renewable resource, i.e., once used they cannot be replaced. Combustion of fossil fuels makes the environment more acidic.
