Study Notes
Coal and Fossil Fuels
- Coal, petroleum, and natural gas are exhaustible fossil fuels derived from the remains of living organisms.
- Formation involves dead vegetation undergoing carbonisation over millions of years, resulting in coal, also known as a fossil fuel.
- In a coal mine, coal is extracted, which can burn to produce carbon dioxide gas when heated.
Products from Coal
-
Coke:
- A tough, black, porous substance, almost pure carbon.
- Utilized in steel manufacturing and metal extraction.
-
Coal Tar:
- A thick black liquid with an unpleasant odor, consisting of over 200 substances.
- Used to produce synthetic dyes, drugs, explosives, perfumes, plastics, paints, and roofing materials.
- Naphthalene balls, derived from coal tar, repel moths.
-
Coal Gas:
- Produced during coal processing for coke.
- Initially used for street lighting in the early 1800s, now primarily for heating.
Petroleum and Natural Gas
-
Petroleum, also referred to as "black gold," is processed to obtain valuable petrochemicals for detergents, fibers, and plastics.
-
Constituents of Petroleum:
- Various products include LPG for fuel, petrol for transportation, kerosene for stoves, diesel for heavy vehicles, lubricating oil, paraffin wax for ointments, and bitumen for road surfacing.
-
Natural Gas:
- An important, easily transportable fossil fuel, stored as compressed natural gas (CNG).
- CNG is favored for power generation and as a cleaner fuel for transport vehicles, reducing air pollution.
Environmental Impact and Conservation
- Fossil fuel reserves are limited, forecasted to last only a few hundred years; their utilization contributes to air pollution and global warming.
- Strategies to conserve fossil fuels include driving at moderate speeds, turning off engines at stops, and maintaining correct tire pressures to improve fuel efficiency.
Summary of Key Points
- Fossil fuels—coal, petroleum, and natural gas—are non-renewable and formed from organic material.
- The extraction and refinement processes yield various important products essential for everyday life and industry.
- The need for responsible usage of fossil fuels is emphasized to mitigate environmental impacts.
