1. Steel: Coal is used to produce coke, which is a key ingredient in the production of steel. Coke is made by heating coal in the absence of air, which drives off the volatile components and leaves behind a hard, porous material.
2. Electricity: Coal is used to generate electricity by burning it in a boiler to produce steam. The steam then drives a turbine, which generates electricity.
3. Coke: Coke is the solid residue left after coal is heated in the absence of air. It is a fuel that is used to smelt iron ore in the production of steel.
4. Gasoline: Coal can be converted into gasoline through a process called coal liquefaction. This process involves heating coal with hydrogen and a catalyst to break down the coal's molecules and produce gasoline and other liquid fuels.
5. Diesel: Coal can also be converted into diesel fuel through a process called coal gasification. This process involves heating coal with oxygen and steam to produce a gas that is then converted into diesel fuel.
6. Chemicals: Coal can be used to produce a variety of chemicals, including ammonia, benzene, and methanol. These chemicals are used to make a wide range of products, including fertilizers, plastics, and solvents.
7. Activated carbon: Activated carbon is a highly porous material that is made from coal. It is used as an adsorbent to remove impurities from water and gas.
8. Coal tar: Coal tar is a thick, black liquid that is produced as a byproduct of the coking process. It is used to make a variety of products, including roofing materials, paving materials, and chemicals.
9. Coal gas: Coal gas is a flammable gas that is produced by heating coal in the absence of air. It is used as a fuel for heating and cooking.
10. Synthetic natural gas: Synthetic natural gas (SNG) is a gas that is produced from coal through a process called coal gasification. It is a clean-burning fuel that can be used to heat homes and businesses.
