- In the coal processing industry, coal is converted into coke by subjecting it to high pressure and temperature.
- This process helps in transforming coal into a tough, porous, and black substance called coke.
- This coke is then used in making steel and extracting various metals.
- Imagine coal changing its form like how ice melts and turns into water when it gets warm.

Coal to Coke Conversion Process
Coal is transformed into coke through a process called carbonization, which involves heating coal in the absence of air. The correct answer is option 'C': by subjecting it to high pressure and temperature. Here's how it works:
1. Carbonization Process
- Coal is placed in a large oven called a coke oven.
- The oven is heated to temperatures ranging from 1000°C to 1200°C (1832°F to 2192°F).
- This heating occurs without the presence of air to prevent combustion.
2. Chemical Changes
- As coal is heated, it undergoes a series of chemical reactions.
- Volatile compounds, such as water vapor, coal gas, and tar, are released.
- The remaining material becomes richer in carbon as impurities are driven off.
3. Formation of Coke
- The solid residue left after the volatile substances are removed is called coke.
- Coke is a porous and carbon-rich material that serves as an essential fuel and reducing agent in the production of iron and steel.
4. Importance of Coke
- Coke is crucial in the steel-making process, where it provides the necessary heat and reduces iron ore to iron.
- It also has applications in other industries due to its high carbon content.
In summary, the conversion of coal into coke involves high-pressure and high-temperature conditions that allow for the efficient removal of volatile compounds, leading to the formation of a solid carbon-rich material essential for various industrial processes.
