What is coal? What is coal used for?

In today's developed industry, coal always holds an important position. In this article, LEC Group will help you better understand what is coal, what is used for coal?

What is coal?

Coal is a sedimentary rock with a black or brown-black color that can burn. Coal often appears in rock layers with many layers or mineral layers.

Coal is a fossil fuel, formed from buried plants that go through stages from peat and gradually turns into brown coal (also called lignite). Next, the lignite will become semi-bituminous coal, then the finished bituminous coal. Finally, transform into coal.

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

What is coal used for? Application of coal to life

1. Used as fuel and energy

To answer the question, what is the coal used for? The main answer is to make fuel and energy. Today, coal is used primarily as a solid fuel for power generation and combustion. Normally, coal will be pulverized and then burned in a boiler. The temperature of the kiln converts the water in the boiler into water. Next, steam is used to turn the turbines and operate generators to generate electricity.

Currently, there is an alternative method of using coal in the electricity generation industry with higher efficiency. That is the integrated gasification combined cycle power plant (IGCC). This cycle replaces coal grinding and burning directly into fuel in a boiler. Coal is gasified to produce synthetic gas coal gasification, which is burned in gas turbines to generate electricity.

2. Used in gasification technology

Coal gasification is used to produce synthetic gas, CO gas mixture and hydrogen gas (H2). Synthesis gas is used primarily to burn electricity-producing turbines. However, synthetic gas is also partly converted into transport fuel such as gasoline, diesel. In addition, syngas can also be converted into methanol.

3. Liquefaction

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

Coal liquefaction methods involve carbon dioxide emissions (CO2) during the conversion process. If in the liquefaction process coal does not use the technology to capture and store carbon or biomass mixture. The result will be a greenhouse gas footprint, especially directly affecting the environment.

4. Refined coal

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

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

5. Use in chemical process

This process takes place when the metal melts in the mold, the coal is burned slowly, releasing the gas to reduce the pressure. Thanks to that that prevents metal from penetrating into the gaps of the sand. In addition, it is also contained in a mold, a paste or liquid with a similar function is applied to the mold before casting. This is the answer to the question of what coal is used for.

6. Application of manufacturing chemicals

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

The main chemicals produced from syngas include methanol, hydrogen and carbon monoxide, olefins, acetic acid, formaldehyde, ammonia, and others.
