FAQs on Useful Products Processed from Coal: Coke,Coal Tar & Coal Gas Video Lecture - Science Class 8
| 1. What is coke and how is it processed from coal? |  |
Ans. Coke is a fuel that is processed from coal by heating it in the absence of air. This process, known as coking, involves heating coal at high temperatures to remove volatile components and produce a solid, carbon-rich material called coke.
| 2. What are the uses of coal tar? | |
Ans. Coal tar is a byproduct of coal processing and has various useful applications. It is commonly used in the production of roofing materials, such as shingles and tar paper. Additionally, coal tar is used in the manufacturing of dyes, paints, and synthetic chemicals. It can also be processed to produce medical treatments for skin conditions like psoriasis.
| 3. How is coal gas produced and what are its uses? | |
Ans. Coal gas, also known as town gas, is produced by heating coal in the absence of air to release gases such as methane, carbon monoxide, and hydrogen. This process, called gasification, converts coal into a gaseous fuel. Coal gas has historically been used for lighting, heating, and cooking. However, with the advent of natural gas, its usage has significantly decreased.
| 4. What are the environmental impacts of coal processing? | |
Ans. Coal processing can have several environmental impacts. The combustion of coal releases carbon dioxide, a greenhouse gas that contributes to climate change. In addition, coal processing can release pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which contribute to air pollution and respiratory problems. The extraction and transportation of coal can also result in habitat destruction and water pollution.
| 5. Are there any alternative sources of coke, coal tar, and coal gas? | |
Ans. Yes, there are alternative sources for these products. Coke can also be produced from petroleum and biomass, while coal tar can be substituted with wood tar or petroleum-based alternatives. Similarly, natural gas and renewable sources like biomass can be used as alternatives for coal gas. The development and utilization of these alternatives can help reduce the environmental impact associated with coal processing.
