What is the Difference Between Anthracite and Coal?
🆚 Go to Comparative Table 🆚The main difference between anthracite and coal lies in their composition, carbon content, and properties. Anthracite, also known as hard coal or black coal, is a more metamorphosed and harder variety of coal with a higher carbon content (86% to 97%) and fewer impurities. On the other hand, regular coal, often referred to as soft coal, has a lower carbon content (45% to 86%) and contains more impurities. Here are some key differences between anthracite and coal:
- Carbon Content: Anthracite has a higher carbon content (86% to 97%) compared to regular coal (45% to 86%).
- Hardness and Luster: Anthracite is harder and has a higher luster compared to regular coal.
- Impurities: Anthracite contains fewer impurities than regular coal.
- Energy Output: Anthracite coal has more energy than regular coal because it contains more carbon, generating more heat per unit of weight.
- Cost: Anthracite coal is more expensive than regular coal due to its higher energy content and rarity.
- Availability: Regular coal is more readily available than anthracite, which is found in only a few countries and makes up about 1% of global coal reserves.
- Environmental Impact: Regular coal creates more pollutants than anthracite, such as sulfur dioxide, nitrogen oxides, and particulate matter.
In summary, anthracite is a higher-quality coal with a higher carbon content, harder texture, and luster, while regular coal is more abundant, has lower carbon content, and contains more impurities. Anthracite is more efficient and cleaner-burning, making it a more desirable fuel source despite its higher cost.
Comparative Table: Anthracite vs Coal
Here is a table comparing the differences between anthracite and coal:
| Feature | Anthracite | Coal (Bituminous) |
|---|---|---|
| Origin | Formed from sedimentary rocks | Formed from younger, less refined coal |
| Carbon Content | Higher carbon content (87%) | Lower carbon content |
| Impurities | Lower impurities | Higher impurities |
| Energy Production | Produces more energy when burned | Produces less energy when burned |
| Hardness | Hard and shiny | Softer and less shiny |
| Ignition | Does not ignite easily, produces a blue, smokeless flame when burned | Easier to ignite |
| Uses | Mainly used for heating buildings and in making steel | Mainly used to generate electricity and in industry |
| Carbon Footprint | Smaller carbon footprint, fewer greenhouse gas emissions per unit of energy produced | Larger carbon footprint, more greenhouse gas emissions per unit of energy produced |
| Air Pollution | Cleaner burning, less air pollution when burned | Dirtier burning, more air pollution when burned |
Anthracite is considered a higher quality coal due to its higher carbon content, lower impurities, and higher energy production when burned. It is mainly used for heating buildings and in making steel. In contrast, bituminous coal, also known as regular coal, is a younger and less refined coal with a lower carbon content and higher impurities. It is mainly used to generate electricity and in industry.
