3.1.2 Products of Coal

Description

Quick Overview

This section discusses the products derived from coal, including coal gas, coal tar, and coke, along with the formation and significance of coal as a fossil fuel.

Standard

In this section, we explore the processes by which coal is formed, its classification as a fossil fuel, and its usage. The products obtained from coal processing, such as coal gas, coal tar, and coke, are discussed in detail, highlighting their applications in various industries.

Detailed

Products of Coal

Coal, one of the primary fossil fuels, is formed from the decayed remains of plants over millions of years through a process called carbonization. This section not only covers the formation of coal but also delves into its multiple derivatives.

Formation of Coal:

Coal is primarily made from carbon, and its journey begins in ancient wetland forests that were buried by flooding, leading to immense pressure and heat. This process transforms dead vegetation into coal over geological time scales.

Key Products of Coal:

  1. Coal Gas: Produced during the processing of coal to create coke. Initially used for street lighting, it is now more commonly employed as a heating fuel.
  2. Coke: An almost pure form of carbon, used in steel manufacturing and metal extraction.
  3. Coal Tar: A thick, black liquid composed of numerous substances, used as a base for synthetic dyes, drugs, and other industrial products.

Applications:

These products not only contribute to various industrial processes but have also played a crucial role in energy production. Understanding these derivatives emphasizes the importance of coal management due to its exhaustible nature.

Key Concepts

  • Carbonization: The process of converting dead organisms into coal under heat and pressure.

  • Fossil Fuels: Natural fuels derived from decomposed organic material.

  • Coal Gas: A product of coal that is primarily utilized as a fuel.

  • Coke: A byproduct of coal processing, vital for metal manufacturing.

  • Coal Tar: A liquid derived from coal used in many industrial products.
