What is coal? What is coal used for?

Coal provides fuel to burn for heat. Currently, coal provides about a quarter of the world's basic energy. And this is also the largest source of energy to produce electricity. After understanding what coal is, now is the time to learn what coal is used for.

Currently, there is an alternative method of using coal in the power generation industry with higher efficiency. That is the integrated gasification combined cycle (IGCC) power plant. This cycle replaces coal crushing and direct combustion as fuel in the boiler. Coal is gasified to produce coal gasification, which is burned in a gas turbine to generate electricity.

2. Use in gasification technology
Coal gasification is used to produce syngas, a mixture of CO and hydrogen gas (H2). Syngas is mainly used to burn turbines to produce electricity. However, syngas is also partly converted into transportation fuels such as gasoline, diesel. In addition, syngas can be converted to methanol.

3. Liquefaction
Liquefaction is an answer to the question of what  coal  is used for. Coal can be converted into a synthetic fuel equivalent to gasoline or diesel by a number of different processes

Coal liquefaction methods involve carbon dioxide (CO2) emissions during the conversion process. If the coal liquefaction process does not use carbon capture and storage technology or a mixture of biomass. The result will be a greenhouse gas footprint, especially with a direct impact on the environment.

4. Refined coal
Refined coal is the product of coal upgrading technology that removes moisture and environmental pollutants. This is a form of some kind of pre-treatment and coal burning process that changes the characteristics of coal before it is burned.

The purpose of refined coal production is to increase efficiency and reduce emissions when coal is burned.

5. Use in chemical process
This process takes place when the molten metal is in the mold, the coal is ignited slowly, releasing the gas to relieve the pressure. This prevents metal from entering the gaps of the sand. In addition, it is also contained in the mold, a paste or liquid of similar function applied to the mold before casting. This is the answer to the question of what coal is used for.

6. Applications for the production of chemical substances
Coal is an important raw material in the manufacture of a wide range of chemical fertilizers and other chemical products. The main method in the primary production of these products is coal gasification to produce syngas.
